Sizing notes

For rock climbing shoes: Choose soft shoes two to three sizes smaller than your street shoe size. We recommend you fit your trad shoes one to two sizes under your street shoe size. Remember to factor in stretch. Unlined slip-lasted shoes tend to stretch about one full size. Lined shoes stretch about a half size. Remember: a well-fit comfortable shoe will work better than an ill-fitting tighter shoe. For boots: Add one half size to your street shoe size. You should be able to slip one finger behind your heel when you are standing up with the boot unlaced and your toes touching the front. If the boot is too short, your toes will get smashed walking downhill. Too long and your heel will slide up and down and give you blisters.

Rated 2 out of 5 by from Not for Front Range trails I love La Sportiva running shoes. I run 10-20 miles at a time, only on trails, and usually in Indian Peaks Wildnerness Area. These shoes are super comfortable, light, dry quickly. The sole so soft that... 1) I never roll an ankle b/c my foot feels the contour and adjusts 2) Nearly every time I run, I injur the sole of my foot from landing on a rock with too much impact. 3) the usual amazing traction of La Sportiva's is only a memory with these shoes- and that memory will get you in trouble. They slide like crazy on dry rock and gravel. I'm not sure what sort of soft, well manicured trail these are made for, but I haven't found it yet.

Rated 5 out of 5 by from SHT Rated I put about 100 miles on these before thru-hiking the superior hiking trail in them, averaging about 20mi/day. The lacing system is superb for quick breaks, and adjustments can be made on the fly. The trail was very wet and the Helios drained and dried quickly. I absolutely abused these shoes while on the trail, and their durability was shocking. No tears or delamination occurred. Rocks and roots can easily be felt through the soles, so step carefully. It is a running shoe after all and not a heavy duty hiking boot. This shoe exceeded my expectations. The pic was taken after about 400mi of abuse.

Rated 3 out of 5 by from Awesome shoe, terrible durability I bought these to replace some generic Asics trail running shoes that had fallen apart after maybe a year. I wanted something grippy with good cushion, but light. These shoes tick all those boxes. I love the lace system, I love the sticky rubber, I love the lightness. Sadly, they've fallen apart in only a few months. The durability is jut not there, and there's only a few millimeters of sticky rubber sole before you get down to the light foam. If you're a trail runner looking for a competition shoe, buy these, but if you intend to wear them for any regular interval, look elsewhere or you'll be buying replacements quickly. One more thing, these run quite small size-wise. I tried them on in a store, but if you're buying online only... good luck.

Rated 4 out of 5 by from Good light shoes for non-technical trail running These are my first impressions of the shoes after running 5+ miles in Southern California mountains. As a reference point I will use La Sportiva Bushido that I have been using in similar terrain for about 18 months. Fit: Helios run half size smaller due to shorter and narrower toe box. I wear 46.5/12.5 in La Sportiva Bushido as well as in Nike Free Run. With Helios I had to go with size 47/13 since 46.5/12.5 seemed too small with my big toe firmly pressing against the front of the shoe. Terrain and Traction: My first run took place in mountainous SoCal. terrain. I tested the pair on Iron Mountain in Poway that features 1050ft elevation climb over 2.6 mile stretch. It’s a hard packed sandy trail with many rocks (some of them are sharp) sticking out of the ground and large boulders. Bushido shoes worked very well on this mountain so I wanted to give Helios a shot. As I began my run up the mountain I noticed complete lack of decent traction. It felt like the shoes slipped on sand and I had to push about 10% harder to compensate for their inability to stick to the ground. Going over rocks was also not as pleasant as with Bushidos — my feet could feel every edge of the rock I happened to step on. Helios’ soles are definitely not as rigid as ones on Bushido. Stability also appeared to be compromised as Helios have more stretchy upper. Running down the mountain I purposely had to slow down and pace myself jumping from one boulder to the next. When I run in Bushidos I feel very secure landing on top of a boulder since they practically stick to rock’s surface. Not so much with Helios — it felt like my foot could slide off a boulder at any time. Verdict: Helios seems to be an excellent and light trail running shoes designed for non-challenging terrain. I imagine they would perform very well on a flat, hard packed trail somewhere on the East Coast in the forest with occasional roots. However, if you happen to run in desert-like, rocky and sandy conditions requiring more traction and foot protection I would look somewhere else. I will give these shoes one more try on a flat trail but keeping in mind that most trails in So Cal have a lot of sand I suspect to experience same problems with traction.

Rated 4 out of 5 by from Light, minimalist runner Light, minimalist but with a nice cushioned feel. Tongue has nice padding so you don't feel the laces. The heel cup is flexible and soft. I ended up returning due to the narrow toe box. I had to go up 2 sizes and it was still too narrow but fit nice everywhere else.
