beats all

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

I have solution, hornet, black wings, G2 predator for aggressive shoes, and this one is by far my favorite. Snug fit, i wear size 8.5 in these, and 9 street shoes, super tight, but surprisingly very comfortable, the only set back is the heel doesn't fit me too well and i have an air pocket, but no 5.10 heels ever fit me well.
Rubber is supper soft and sensitive, so soft that i feel comfortable climbing slab in these (you read that right, slab).
Love the color. definitely works best for over hanging routes, but i wear these for any climb, even multi-pitches. This is the perfect shoes for me, it's the tits.

Could anyone comment on the sizing compared...

Could anyone comment on the sizing compared to the anasazi vvs, moccasym, dragons, or sportiva solutions?

Responded on

My solutions were sized a 38.5, and my dragons were an 8.5. According to La Sportiva's chart, that's the exact conversion, so they size about the same. When I got them each initially, the Solutions fit tighter than the dragons, but they stretched out more and both ended up fitting exactly the same. I could even wear them both without lacing them up. However, I went back to LS because I felt the heel fit me a lot better--the Dragon heel was a little less fitted and therefore a little loose. In my experience with Five Ten (also had Moccasyms) they fit the same for the type of shoe you want--which is to say that my 8.5 Dragons were nice and tight but my 8.5 Moccasyms were very comfortable. I've heard from friends that the Moccasyms and the Anasazis are extremely similar in fit. Hope that helps!

Quantum tripp'n

  • Gender: Male
  • Fit: Runs small

Outstanding shoes that fit great, feel a little wider in the toe area than the Hornets. Had to go 1.5 increase in shoe size over my normal Anasazi 11.5 climbing shoes. New they fit slightly snug over the second toe, but do relax slightly and fit great after wearing. I find this upsizing true with other downturn concave toed shoes as was with the Hornets. I agree with Dem's & Roy's size comments also. Not thrilled with the purple color but function wins out over looks. My Hornets were eye candy and functional. Top line on the Quantums, they are Killer shoes!

this might seem unusually specific, but...

this might seem unusually specific, but does the rubber on the quantum cover the middle toe knuckle? i currently wear the anasazi lv (sized very tight), and my middle toe knuckle screams on hard toe hooks because there's just a thin layer of cowdura between it and the rock. it's hard to tell from the pictures and i also have very limited experience with the fit of downturned shoes. any help is greatly appreciated, thanks!

It does cover the middle knuckles pretty well for toe hooks. The only gap in coverage is between the big toe and the next one. I pulled this photo off of the Five Ten site so hopefully it illustrates the area you are asking about.

Great shoe, just need to break them in.

  • Gender: Male
  • Familiarity: I've put it through the wringer

These are my second pair of shoes and first time trying a shoe with an aggressive downturn toe. At first I was not too impressed. Feet would slip under roofs, couldn't toe hook. But after breaking them in I love them. Super sticky, great edges, not the best for cracks but can still handle slabs despite the downturn toe. All reviews I've read said the synthetic uppers will not stretch out. When I got them they were so tight I could barely lace them up. But after a month of good climbing they did stretch out perfectly. I'm glad a didn't size up. My heels will pull out if I'm cranking on a heel hook. I've had them for 6 months and the toe is worn and peeling. But overall the rest of the rubber is still holding up great.

Way Cool!

  • Gender: Male
  • Familiarity: I've put it through the wringer

These shoes kill! The only knock I can come up with (and this is for the real nitpickers) is that the heel has a little dead spot, no matter how tight you size them. The great thing is you do not have to size them too tight for performance. See the full review here:
I cannot recommend these shoes strongly enough. For an American-made produce (if that matters to you) these are as good as it gets!

I've worn alot of shoes over the years, my favorite hands down was the Moccasym. I believe this is my new favorite shoe i will use as my go to shoe. Personally i am not a huge fan of the overly aggressive down-turned shoes but for lack of a better word i do like a "medium" aggressive shoe and i feel like the Quantum is just right. I ordered 1.5 sizes up from my street shoe(10.5 to a 12.0) and they were a perfect fit, a little snug and with just a hair of stretch they'll be perfect. I dont have the widest foot but i dont have a narrow foot either so i'd say for most people whos feet are just a little wider than normal 1.5 sizes up is a good start. these things are already comfortable and they arent broken in yet. Its aggressive enough to get on very small edges and on small slick sloped holds, but not overly aggressive that you cant smear properly or feel the urge to yank them off half way through a climb, you'd swear you had a huge foot hold underneath you on some of the shakiest holds.. these things seems to expand and contact every available centimeter. Overall everything seems real solid, the laces are strong and you can really cinch these puppies down without fear of busting through an eyelet. The inside is not extremely minimalist like some of the Sportiva models, its got what i'd call a thin layer of padding but its perfect, i can still feel EVERYTHING. When you get them you'll notice a pretty substantial down hook on the toe, that thing grabs like a monkey hand. After several climbs i was very impressed with this shoe, i'll be buying them until they discontinue them for sure. i want to say its an all-around shoe but that seems to take something away from how sweet these things are when doing anything technical, its an all-around shoe without the all-around shoe look/performance. so far its been dead on for bouldering and technical climbing. no cracks yet but its got the rubber on the toe for it, though, you might have to size them differently for all day crack climbing.. Oh, and these things look sick to boot. get these!

great shoe

Out of the box and straight onto the rock. After only a couple of short overhang climbs felt comfy enough for long sessions. Went 1.5 sizes up from my green Verdes and fit just right, could even go another .5 size up. Rubber sticky as, and holds to the tiniest edge. Of course not so good for the vertical walls or slabs but will get you thru those sections to the next steep part without hammering yer toes too much.

When are you going to get in more sizes?...

When are you going to get in more sizes? Like say a 7.5

Very precise "low-volume" shoe

This is a great "low-volume" lace up. For such an aggressive shoe it would be nice to see a Velcro version as you'll most likely size these babies to tackle your hardest routes... Still highly recommended till the perfect shoe is born :)

the anasazi arrowhead is the velcro equivalent to the quantum

I'm looking into these. Anyone know how they compare to the Verdes? It sounds like they're better for bouldering.

Best Answer Responded on

They're definitely more downturned than the Verdes, and they'll have a more agressive fit as well. Much better for bouldering, not as good for long days on big walls.

Responded on

As Angus said, these shoes are very downturned. They are a slim, sleek, and low profile ankle shoes. I went the same size as my street shoe and found the break in time to be very painful. These shoes were meant to crush hard overhung routes/boulders.

Responded on

I have both the verdes and the quantums and LOVE both. the quantums are more downturned and are a much more low volume shoe. I use the quantums for hard sport climbing and the verdes for multipitch routes.

how about smearing with those ? is it...

how about smearing with those ? is it really an all-around shoe , but a bit downturned ? what i really like for example , with sportivas , is that , even with downturned models ( solution) you can be sure that you use everything from smears to edges really well if you need to. But with 5.10 downturned models ( teams ) you feel like a cripple when it comes to smearing or a more vertical terrain ... so ? is it
THAT good for rulling over anything it may comes in your way ? thank you .

Responded on

I've had no problem getting great smears with these. The downturn isn't as drastic as other shoes and allows you to get some great surface contact while smearing. Definitely a much different shoe when compared to something like a Team.
I own both Teams and Quantums and my teams rarely see any more use now.

The stars speak for themselves

Being a boulder junkie myself, i have loved every aspect of this shoe, heel hooks up great, edging is spot on same with the toeing action and of course amazing rubber. i have narrow feet with my left one being slightly larger so I ended up downsizing a full size from my street shoe which made them a bit painful at first on the left foot, after a few sessions they fit great.

Size to U.S. street shoe

crazy downturned shoe with sensitive rubber. did not climb more than one day with them because they were too small. if your wondering what size to get, it would be good to start with your U.S. street shoe size. the synthetic upper does not stretch.

Test Proven!

Just got back from a weekend in Rumbling Bald in NC and after 3 days of bouldering morning and night, I can vouch for the performance and endurance of these shoes. I switched to these shoes from 2 pairs of Evolv Optimus Primes and while the Primes were much more comfortable for my wide feet, as they were A) Only a half size down from my street shoe, and B) Designed to be a little bit wider, but a little less aggressive.

The 5.10's are a full size down from my street shoe of 9.5 wide. I have a caveman foot and it makes shoe shopping, and even moreso, rock climbing shoe shopping very difficult. The Quantums stretch out a ton on the sides and even on the heel area to allow my fat foot foot to squeeze in, albeit, with a good bit of initial struggling. They do require a bit of a break in period to get the maximum potential from the rubber, again, another difference from the Evolv's Trax rubber, which was good out of the box, but had an extremely short lifespan in the toe area. I primarily boulder indoors so the walls aren't nearly as aggressive as real rock; the rapid decay of rubber was very disappointing to me. The Quantums Stealth rubber however has help up fantastically through many indoor boulder sessions, to break in the rubber and to help send some long term projects, and also through my weekend of spirited climbing outdoors and very sharp granite.

The Quantums were GREAT at finding and sticking to tiny foot jibs that my old shoes were guarunteed to pop off of. Some examples of small crystal foot problems, done this weekend are, Don't Run- V8, Rotator Cuff- V5, Chris Klein's Corner- V5. and Torque Master- V6. They are very downturned and very aggressive and take a bit of adjusting to get used to. But once you figure out how to press in with the toes the shoes won't let you down.

They were also very good at holding some pretty intense heels. They held well on Brackish Water- V8, a V8 sit start technical problem with I forgot the name of in the cluster area, and the double heel hook beta used to send Patio Roof-V8.

I can't say enough good things about these shoes. Yes they hurt like crap for someone with wide feet. Yes the heel does cut into the ankle a little as they have the low heel design of the older Anasazis. Yes they do have a tough break in period. But you know they're worth that every time when I finally get them on and know that I can trust them to get the job done on my projects. You sold me 5.10, great job Quantum; I'm looking forward to a future with more sends.

I don't give 5 stars to gear often unless it's really deserving, but the 5.10 Quantum deserves the 5/5.
Based on the popular 5.10 Anasazi, the Quantum adds a downturned profile, low volume heel cup and the amazingly sticky and tactile Stealth Mystique to it's previous popular design. These shoes are freaking weapons. I've climbed on them for a few weeks now and I have really nothing but praise for them. The aggressive turn of the shoe make tackling overhanging and technical routes a breeze, and they edge like a fiend on slab and tiny little features. They even jam in cracks relatively well. I haven't put these through a maneuver yet where I was left wanting more out of a shoe.
The Mystique rubber is some of the stickiest and best tactile transmitting rubber I've ever felt (I prefer it over the Onyx rubber as to which one is "better") so I always can feel what my feet are doing on the rock without having to guess.
Comfort-wise, I find that these are very easy to leave on for hours without having to take them off or even untie (your climbing partner will be happy if you're one of those knuckle draggers who takes your shoes off after every climb). For fit, I had to size up 1.5-2 from my street shoe and they are snug, but not painful (very important as these will not really stretch much at all). I have absurdly wide feet though, so you probably will be able to get away with less.
If i had to say something negative about the shoe, and I'm really nit picking here, is that the heel cup rubs on the back of my achilles and starts to get annoying after a while. This happens with most of the other 5.10s I've had though and gets better after a few weeks of climbing in them. It's just the way my foot is shaped. I put a small piece of climbing tape over the lip of the heel and it ceases to be a problem.
These are my new go-to shoe for general cragging and gym climbing. Wicked precise and sticky, the quantums have really made an impression on me of what a good shoe can do for your climbing; dare I say...give it a "quantum leap?" ;) A perfect shoe for those looking for a more technical shoe to supplement their first basic pair, or the seasoned climber who's been sending projects for years.

Try them if your looking for a more aggressive all-rounder, you won't be disappointed.

How do these fit compared to the Teams? I previously bought Teams in a 10 1/2 and sent them back because they were way too tight. However, I've also tried on the Anasazis in a 10 1/2 and felt that I could easily downsize to a 10 in those. Suggestions for fitting the Quantum? I'm really tired of sending shoes back and losing money on shipping.
