Trail runners with a purpose.

The La Sportiva Men's Helios SR Running Shoes are minimalist, supportive kicks ideal for your next training season. The uppers are made of HyDrain mesh and Poly Grid for excellent breathability and the ability to shed water and excess moisture as you run. An EVA AirMesh lining further helps to keep your feet feeling fresh as you crush the miles. A MorphoDynamic injected-molded EVA midsole, combined with a 2mm LaSpEVA footbed, offers excellent support and cushioning for those long days on the trail. In case your run features slippery roots and rocks, La Sportiva used FriXion AT rubber soles for stellar traction in wet conditions.

Minimalist maybe...

  • Fit: Runs small
  • Size Bought: 46.5
  • Height: 6'3"
  • Weight: 215lbs

This is might qualify for a minimalist design but it is built like a tank and protects the feet very well. Definitely runs a full size small, I wear an 11.5 and I ordered the 46.5 (12.5 Euro), also plenty of room to slide your favorite insole in without stressing the shoe body. Great buy at 40% off

Great shoe

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

Awesome minimalist running shoe. I used it with no insole and ran in it till I wore through the soles. Long trail runs, Scrambled in it, used it as an approach shoe. Just a great mountain shoe. I went up half a size from my normal running shoe.

Love Helios SR and love service of BC

    1) There are no best shoes for everyone, we all have different feet and therefore every human being should find their best pair, this one is the top notch for me.
    -Good things:
    -Very light, if you run 100 mile race you want to have the lightest possible shoes on your feet. There are no benefits of having an extra weight on you, especialy on the body parts that are moving.
    -Protection, I have heard that people are complaining about not having rock plate in them....I ran ES 100 twice in them as well Crewel Jewel 100 and do not feel need ....but again we all different.
    -Soles on them grip very well , very flexible and I feel they have enough cushioning .

    Now weak point....after two of my 100 milers soles at the toe box started to come apart, either it is quality of glue or rocky terrain but that what it was...I contacted backcountry and Natalie from their warranty department fixed my problem very quickly with new pair of shoes sent to me.

    Best trail shoe

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 44
    • Height: 6'1"
    • Weight: 155lbs

    Hands down favorite running shoe. Not only are they lightweight but they fit my feet perfectly. The Helios has great traction for coming down steep trails. I've owned four pairs and had to make the switch to the bushido because I thought la sportiva stopped making these. Traditional laces. I will definitely purchase another pair.

    Descent shoe

    • Familiarity: I've used it several times

    Not a heavy-duty runner. Definitely the weakest "rock plate" I've seen in a shoe. Seriously, is it even there? It really lacks talus type protection. Okay for 5–10 mile outings or scrambling/clipping off to a harness but not much more. Fit is better around the heel and midfoot and better lacing than the original helios, but the toe box is too narrow. Sticky rubber is cool.

    These are a bit of a niche shoe - they're quite minimal but designed for rocky, technical terrain. If you cover a lot of vert, have experience with minimalist shoes, and you're light on your feet, you'll probably like these. These are definitely NOT what you're looking for if you're just getting into trail running.

    The first thing I noticed was that they're featherweight light. I had to check the box to make sure both shoes were in there. The second thing I noticed was that they're a very aggressive fit. Plan on sizing up a half to whole size depending on how tight you want them. I wear a 9.5 in almost all running shoes. I started with a 42.5 but had to size up to a 43 which provides a snug but comfortable fit. The fully gusseted tongue really wraps your foot securely and foot movement within the shoe is non-existent.

    Easily the grippiest running shoe I've used on any type of dry rock - 5/5 for grip on rocky trails and ridge scrambles. Grip is better than average on wet rock (notoriously difficult to get good traction on) but they don't have that glued-to-the-rock feel anymore and slips are possible.

    The non-conventional lug design does better than you'd expect on loose sand and gravel, but is not on par with more aggressively lugged shoes. Definitely their weak point as far as grip goes. They'll still get you up and down steep loose terrain, but you'll need to be pretty on point with your footwork if you're moving fast.

    The amount of protection these provide is minimal. The midsole is on the soft side and I'm expecting it to pack out relatively quickly. The toe is not very beefy and you will be painfully aware of any rocks or roots you kick. They allegedly have some sort of very minimal rock plate in the forefoot and nothing in the heel. In the real world they don't feel like they have a rock plate at all and if you stomp on sharp rocks it will hurt. I feel like I absolutely fly in these shoes and the times I've been putting up on some of my favorite local runs supports that, but my feet have been feeling a little beat up afterwards.

    I've been a quick to point out the flaws with these, but overall, I'm extremely stoked on these for mountain runs and scrambles with lots of vert. The light weight and precise fit lets you absolutely fly up and down technical climbs as fast as your legs can handle - just watch where you step. They'd be a fantastic race day shoe for sub 20 mile races with lots of climbing. I'd personally choose a beefier shoe with more of a rock plate for ultra distances.

    Footnote for shoe geeks - these are actually 2mm drop with 16mm at the heel and 14mm at the toe according to La Sportiva.

    Photo from the last couple hundred feet of scrambling on the Grand Teton. We didn't do much running up there but they sure stuck to the rock well :)

    Perfect fastpacking/scrambling shoe

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 46.5

    I have taken this shoe out on a couple of long day hikes so far and it has been everything I've been looking for. It is comfortable enough to hike the long miles on trail but also grippy enough to scramble on rock and snow. So far I have taken it out into the Sierra's on wet granite, trails with lots of sharp rocks, steep soft snow, and steep dry granite. This shoe handled all with ease and definitely gave me more confidence. I had been using the Altra Lone Peak's prior to the La Sportiva's and those fit well but had terrible grip on Granite, especially wet granite, not these-the grip with this shoe is insane!

    As for fit- order a full size up at least. I am a 11.5 US and ordered a 46.5. It was a little tight in the beginning but that is to be expected. After 10 miles I don't notice any tightness. The width in the toebox is good after the initial break in period. This shoe is also super light weight. I think I finally found my shoe for long peak bagging days that require a long approach!

    Edit: After using this for a season I am editing my review. These shoes were to small and not wide enough after feet swell from long hikes. Order at least 1.5 US sizes up from normal.

    No Rock Plate?!

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 46
    • Height: 6'0"
    • Weight: 175lbs

    This has to be my dream trail running shoe, except for one major oversight - there doesn't seem to be a rock plate! (descriptions around the net say that it does)

    The stack height is lower than the (non SR) Helios by a few mm, which makes things a tad touchy on rocky terrain. If you look at the bottom of the shoe, the outsole is not continuous - it has major gaps between the rubber, revealing the midsole.

    This is fine, and makes for a very flexible shoe (which I seem to prefer), but it's too easy to get stabbed in the foot with sharp objects that go in between the outer rubber. Ouch. Def. getting an aftermarket rock plate to put in here. The revealed midsole already is looking a little beat up.

    Don't take my word for it. Take out the insole, and see if there's anything between the bed of the shoe and the midfoot. I can personally feel my fingernail through it.

    Other than that, It's an OK scrambling shoe, and I've taken it on 5.easy Flatiron terrain here in Boulder. Although it can't edge, it can smear pretty well. Slightly better grip than the regular Helios. Not sure you want climbing rubber on a trail runner, anyways! Hoping that I could replace an approach shoe with this, but there's def. advantages of a true approach shoe.

    Ran a 50k with them, with an alright time, straight out of the box. They felt great. This is a very lightweight shoe, make no mistake. Things seem to be getting pretty crushed a bit quickly.

    Used the same size (46) for the Helios, Helios SR, and CLite's from La Sportiva - about a size up than say, a Montrail trail runner.

    I was under the assumption that this shoe had a full rock plate, as well. I just double-checked the specs, though, and it just says it has a forefoot rock guard. Glad I checked on that before I decided to buy it.

    Great for buff singletrack and slickrock

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: 41
    • Height: 5'8"
    • Weight: 130lbs

    These things are super light and have a cushy feel. The SR's eat up dirt singletrack and slickrock, but larger sharp rocks will eat you because the foam midsole offers little underfoot protection. Same for overall foot protection so rocky scrambling can be sketchy. Snug fit sized comparable to Anakondas, but shoes are stretchier and have less top/side protection so they are generally more comfortable.

    Perfect Mountain Shoe

    For the last couple of months this has been pretty much the only shoe I have run in. So far my pair has a little over 300 miles on them and aside from the expected wear on the sticky rubber they are going strong. I am so psyched to have a shoe with truly sticky rubber, and dang it is sticky! I just wrapped a 10 day trip to central Peru and spent a lot of time running on very rocky paths with thousands of stone stairs. The traction gave me the confidence to really get after it. Even on a drizzly wet run near Macchu Picchu the shoes grabbed any surface I threw at them. The midsole is very comfortable and transitions nicely from road to trail. It has just enough rock protection to keep some trail feeling without any painful jabs. The upper fits like a glove, I do have narrow feet and often find it hard to keep from slipping side to side. These Italian beauties lock my foot in place. For the first time in several years I have all of my toenails since I am not jamming into the front. I normally wear a 10.5 in most running shoes (new balance, nike, salomon) and I went with the 44 to keep a little extra space up front for very long runs. I am really looking forward to putting them to the test during some long alpine running this summer once the peaks clear of a bit more snow.
