Perfect for the trail

  • Gender: Male
  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've been using this shoe on the trail, on the street, general exercise, and I've put it through the wringer on multiple continents in a wide variety of terrain. As far as the sole and tread goes, it is great for pretty much anything except technical climbing, icy surfaces, and wet indoor surfaces like tile. The construction is solid and the fit is ultra true to size. Keep in mind the plastic heel last when choosing your size as it stays very true to the original size over time. The lacing structure allows for great adjustment and adaptation to foot shape. I currently have a BOA system on mine, but the laces work just as well, if not better. An added bonus is Sportiva's sick color schemes.

Toe Box has Grown I Think

  • Familiarity: I've put it through the wringer

I am on my third pair of these because they have worked really well for me. The morpho dynamic sole has done the trick to eat up rocky trails. I have not had any problems with feeling pointy rocks through them. They are super snug on my foot. I did not have to get a larger size as some have said, so maybe I just like a snugger shoe. However, this third pair (green) seems to have a noticeably larger toe box. I don't like it at all actually as now my forefoot can move around and does not feel locked in like on the previous two pairs. I have tightened the laces all the way down and still have the same problem.
In summary, I probably will not buy these again unless putting a different insole in snugs them back up again.

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

Ok its rare I write reviews but this shoe compels me to jot a few words. I run alot and exclusively it is on dirt and rock trails steep up hills and down. For the last year or so I have been using the Salomon speed cross which I found to be a great shoe, however I am a heavy heel striker esp the outside heel due to my bow legs and hence I was finding that the speed cross was, with is knob design for traction, wearing out very quickly. I have been out on around 15 runs now with the La Sportiva Quantum Trails shoe and find the shoe has no perceivable wear on the outside heel section. The foot is held snugly and yet the laces dont feel like they need to be very tight across the mid foot area to hold the foot. The cushioning Im finding is quite amazing as I feel very little of the rocks and debris I run over and the sole seems to create a very stable running platform. So far I have noticed no slipping on the dust and dirt that I run through. I cant say what they are like in wet mud conditions but for the conditions I tend to run in they provide great grip so far. Size wise I read a review that said that you should go a half size bigger....I would have to agree with this. I am normally a 45 in pretty much everything. However the first pair I purchased I found after the first run that wearing socks made them too tight and I got a slightly blacked 3rd toe. Since then I have been running in them barefoot and they are snug and firm. The second set I purchased I got a 45.5 and these fit perfect with socks.

What's the point of this shoe?

  • Familiarity: I've put it through the wringer

FIrst let me say I love most La Sportiva shoes. Just not this one. I don't get the point of this shoe. First the good: It looks cool and feels super comfortable - almost like a tight slipper. And is nice on flat, smooth terrain.
Now the bad: It has NO traction. This is true of anything wet, including both rocks and wood. And in mud its horrible. If you are climbing a steep trail with loose dirt - forget it. Also, the sole material is so soft, I feel every pebble which makes this a very unpractical shoe for me on technical terrain. Basically everything the promotional material say this shoe was made for I find totally the opposite. What gives? Everything else La Sportiva makes is awesome!

So if you want a very comfortable shoe for running smooth flat surfaces that looks cool, this is the shoe for you. Otherwise look at Raptor or Wildcat if you want something for really technical terrain and like a bit more beef, or the Helios, which in my book is awesome for almost all terrain once you get used to them. The vertical K is a lot lighter and still a much better overall shoe. I'm not shoe expert and don't care to understand all the geeky details, but I've worn out lots of shoes and spent lots of time moving on my feet and I simply found the quantum a real disappointment and an unpractical shoe.

a pretty good shoe

  • Familiarity: I've put it through the wringer

I got these because they are 4mm drop, and they have the perfect amount of rigidity in the sole for me ( i have tried a lot of shoes and i would say medium rigidity). I could buy a more durable mountain running shoe but the soles on these shoes are great for running down hill, because of their temperpedic-like absorption. the uppers are really great and the lacing actually is more durable than it looks.

for barefoot runners these probably feel like high-heels and a bit unstable.
to make them stable in my book, i run them without footbeds.
the grip is mediocre, but a compromise i am willing to make.
i tore the sole of my first pair after a decent 2 years of use, and i am ok with that but i do see the potential for the sole being punctured as it is only a mm thick, and once the foam inside the sole is exposed water gets sucked into them and will not dry until the next day( if in the sun).

i have a very average foot a bit flat but i am sure after running these in rain they can morph to fit well on slightly above average wide and high arched feet. they brake in without losing cushion. that's another plus these shoes stay bouncy as if new for two years, but unfortunately they are not very stable, durable, or grippy.

I am a size 10 for about 20 different articles of footwear, the only things i ever had to size-up one size were my high altitude boots and these shoes. kind of annoying sending them back twice to get the right size.

i am hoping to find a grippier and more durible shoe and i definitly think these are my last pair. i had to get them again because, like i said the cushion is dense but plush, it is hard to explain, they really are different from any other sole and give my stride an extra bounce.

La Sportiva/Quantum Trail Running Shoe

  • Gender: Male
  • Familiarity: I returned this product before using it

The La Sportiva Trail Running Shoe has outstanding style. That is what caught my eye when I was looking to buy a pair of train runners. Unfortunately for me I have a pretty wide foot. I tried the shoe in three different sizes, including an extra wide size in 10.5 and then in an 11. All three sizes were just to narrow on my feet. I had the same problem with a pair of La Sportiva hiking boots. So my advice is double check the width before you buy this brand. They are a great shoe, great style, built to last but they feel to narrow compared to other brand in the same size.

Too tight

  • Familiarity: I returned this product before using it

Saw the price on SAC and purchased instantly, La Sportiva for $50! Sign me up. I just wish I would have read the reviews first. Pulled these outta the box and was instantly worried about how small they looked. Put them on and the worry turned to dread. My first return in the several dozen SAC orders. These were just WAY too tight. I don't know if sizing up would fix the problem, these seem to be designed for a low volume(skinny) foot. I never thought my feet were particularly wide, oh well . Other than that, this shoe was pretty good looking. The sole is completely different than any other shoe I've seen. So in the looks dept. I would give them at least 4 stars, but due to the very odd sizing I give it a 2

Forgot to mention sizing. I'm a pretty consistent 12(us). I purchased these in a 45.5

The Good, The Bad, and The Ugly

Just to preface, I'm 5'10'', 175lbs and in excellent physical condition.

The Good: cool concept and colors

The Bad: unusual fit (lacing and balance) and sizing

The Ugly: produced overpronation and screwed up my left foot, knee and back in one 6-mile run. Time for some Advil.

Two stars is generous.

As far as look and quality go, this looked to be an awesome shoe. I was super pumped when I saw them in person; better than expecting! Then I tried them on? What a disappointment! I have had many pairs of La Sportiva runners and am a size 9 and always get a size 42 and fit flawlessly. These shoe are not on par. They are very narrow and tight fitting so much that I had to return them. I have some what of a wide foot but never had issues in the past. I also got my wife a pair and she had the same issue and she has a slender foot. May work for others but there is a definite issue w/ sizing here! Sole was a little funky as well, felt weak in the heal to me, too soft and there didn't appear to be a lot of rubber there and would wear out quickly. Probably why the sole is splitting in the other review. Two stars just cause La Sportiva is awesome! Move along and get a pair of Wildcats or Raptors can't go wrong there!

A shame

  • Gender: Male
  • Familiarity: I've used it several times

3.5 months used to walk my dog on the streets of CT twice a day for an hour each walk. The soles have several tears on both soles. Very dissapointing.

A shame

hey joeb, the soles are not really made for walking on paved roads/streets they are made for loose dirt and what not. the rubber is so sticky that when you walk on pavement you are basically applying a grinder to the soles.
a nice example is with race(circuit) tires for motorcycles. they are also made of special extra sticky rubber if you use them on normal asphalt you will have to change tires every 20 miles.

with other word they are not made for the job at hand. just get yourself a nice pair of regular walking shoes and you'll be fine :)

Nice shoe, Runs small

This is my first pair of La Sportiva shoes and I thought I'd try them because of a good sale price, so they weren't purchased with a specific task in mind. First off they are super comfortable, hug my feet and fit like a glove. They do run small and narrow though and I'd suggest ordering a half size up. They provide a bit more cushion than I'm used to but am adapting and like the way they work on dry terrain, be it dirt trails, rock, or whatever. I do find that they don't feel nearly as stable though in wet conditions. So I plan to focus using them when it's dry and expect to get lots of good use from them.

Run about a .5 to a half size small

  • Gender: Male
  • Familiarity: I returned this product before using it

i think these would have been a great trail shoe, the 10.5 was way too small & felt like they run about a size small. I usually wear a 10.5. If i order these again, i'll get an 11 or 11.5

Not for snow & mud

My other half has these, b/c they are pretty much the only shoes that would fit his narrow feet. We run the same trails together, me in my Salomon Speedcross 3's, and him in these. And I can tell you that I feel much more surefooted in my Speedcross than him in his Quantum. He gets frustrated when he'd take 2 steps forward and 1 step backward in snow, whereas the Speedcross has super deep and big rubber lugs on the outsoles to keep me from sliding and slipping. Same thing in mud. So if mud & snow is what you do, I'd recommend something else other than Quantum

My other half has these and wants to order...

My other half has these and wants to order a new pair, but couldn't make out the size tag anymore. The only thing he can make out was 10.5 UK. Anyone know what the equivalent size is for these shoes?

In general, UK is a full size smaller than US sizing. So the shoes would be an 11.5 US.

These shoes felt a bit strange at first but after a few runs they felt great. I especially like the tighter fit and the thicker heel which works great for heel strikers like me!

great shoe.

i've owned these for 4 weeks now and put over 100 miles on them. this shoe really shines in technical terrain. coming from cascadias, it took me a few runs to get used to them, they're a more cushioned ride. i didn't like this at first, but i'm finding i'm starting to reach for this shoe more often. the way the upper is designed to fit is outstanding. they really put time into designing a last that fits well. lacing is solid, no slip or laces that continually come undone. size up a half size. i normally wear 46, the 46.5 was the right fit. grip is excellent and confident in all terrain. in lots of mud, they slip just like any other shoe. they do shed mud better. with my cascadias, the spring mud hangs onto the tread for a long time.

i like the shoe best when the trail is rocky and/or a lot of vertical. buff singletrack, then the cascadias come out to play.

Go hit the trails.

This shoe is my first from the La Sportiva mountain running line. I've never owned a pair of La Sportiva's before other than my very first climbing shoe, the Nagos. With my inexperiance stated, I'll go on to say that these are my favorite pair of shoes I've ever owned. I couldn't be anymore happy with the fit, feel, and the way that they preform. The Quantum, one of La Spo's two shoes utilizing their Morphodynamic technology, is extremely comfortable and shock absorbant. The Frixion out sole is grippy and flexible, while still being highly durable. Over all the upper breathes quite well, and still protects against mud, dirt and light water. A very well rounded trail and mountain running shoe is what La Sportiva crafted when they addded this piece to their arsenal of preformance footwear.

My personal experiance: A day or two after I pulled them out of the box, I thew em' on and hit the trails. I couldn't be more pleased. The first thing I noticed about the outside of the shoe was the unique style and colors. I chose the typical yellow and black. The lacing system is very cool, and incorporates a zig zag pattern the laces feed through, this allows the laces to tighten the entire mid section of the shoe. This system that wraps around your foot, already makes the shoe feel like a second skin. As I put them on and tighted them up, I noticed the breathibility of the upper sole, which is perferated in two places, keeping your foot cool. I couldn't wait to run in them, so I did. It was a squshy day on the trails, and I heard these shoes dont preform well in mud. Hmmmmm. I dont know what mud other people were running in, because these worked great. Evenn with the smooth, wavy out sole. The shoe stayed stable, and true to my foot as I lept over big puddles and trudged though dirt. Whats more, is that I even tested the morphodynamic technology's legendary adaptability. to get to my trail head, I ran along road sides on cement, then on gravel and flat, compact dirt. Then finaly to juicy wet trails, then back again. What suprised mr most is that slowly I could feel the sole remembering the shape of my foot, and soon I felt like I was stepping in the same spot over and over again. Then I realized I was stepping on rocks, then back to cement, and more rocks. Bottom line... Adaptable. Above all else. I couldn't belive my eyes or my feet.

I love my new shoes. I hope you will too.

Dont know who to believe...

I've heard...

Dont know who to believe...

I've heard that these shoes can't handle wet and muddy terain, which makes alot of sense due to the smooth wavy out sole. Neverthess, Frixion rubber Ive used in the past, is usually very grippy and durable. I'm wondering whether to buy this shoe, and so far the reviews are a bit confusing. These shoes I've been told both that these things totally rule, and totally suck, and I dont know who to believe.

Also how do they grip rock and other rough meterials? Ill use them as an approach shoe aswell.

Thank you!!

I disagree with the comments that it doesn't have traction. If you're talking a wet root or wood, I don't know a single shoe out there that would grip that so those complainers need to shut it. These shoes grip rocks and dirt well- even in wet conditions. I'd suggest these for running and as an approach shoe as well.

i completely agree with jeff. grip-wise the tread on these is no different than most other shoes in mud/snow. they'll slip just the same. i will add that they shed mud a lot better.

For mud & snow, check out Salomon Speedcross 3's. The deep and huge rubber lugs on the outsole really work in these conditions. I ran through the past winter season in the Salomons without having to put on any traction device in snow. The Quantums on the other hand felt like taking 1 step forward and 2 steps backward on snow.

So if you want a very comfortable shoe for running smooth flat surfaces that looks cool, this is the shoe for you. Otherwise look at Raptor, WIldcat, or Crosslight - all incredible shoes.

very comfy shoe

Bought a pair of the Quantums last summer. They aren't the usual La Sportiva shoe in that there's a whole lot more cushion on the sole. The thing I like about these is that you can hammer a downhill section of trail and not worry too much about how bad your feet will hurt. The traction is great provided you're running dry trails. If you take these into snowy or muddy trails, watch out, the traction really sucks. Still, I really like them for my summer running.
