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 4 out of 5 by from My 2nd pair. Love, but one thing... This is my second pair of La Sportiva Helios. The first pair was from 2015, and I wore them for trail running only for over a year (too long, but I procrastinated on replacing them). Because I loved them so much, I ordered this new (2016) version 2.0 in the same size (women's 10 US/42 UK). Two things I noticed immediately that were different from last year's design is that the 2.0 has a the soft heel counter (instead of a hard heel cup), which I think I like. The other change is the slightly narrower toe box compared to the first version. Because it's slight, I don't think it's a deal-breaker, but I may exchange them for a 10.5 US/42.5 UK. Unfortunately, REI doesn't seem to have this half size larger. Another well-known online competitor does have 10.5 and up to women's size 11 US/43 UK. Aside from the slight changes mentioned and the sizing, this shoe is lightweight and flexible...just what I like in trail shoe, but it doesn't give up any stability in the process (no ankle-rolling!). I ran many trail races and and on all kinds of terrains and weather in my Helios. They were grippy without being too knobby and I like having a good feel for the ground while still having some cushion and this shoe meets my criteria. I did try on the more rugged La Sportiva Bushido, but found it too stiff for my liking and a bit heavier than I prefer. I do like that the Helios 2.0 has a dark colored midsole/side rather than last year's white. No trail shoe should have white anything! So thank you, La Sportiva for making that change. Do NOT wear these for road running, because you will wear away the tread much more quickly than on trail.

Rated 5 out of 5 by from Great shoes I have 2 pairs of these shoes and am going to order another. They are comfy right out of the box - able to hike 10 miles without any blisters! I have very finicky feet after achilles surgery, so the soft back is a plus. I throw some over the counter insoles in there and they are comfortable for miles! Highly breathable so your feet don't cook during the summer. Not sure about durability yet, but I've had mine through the summer and there is no sign of them failing. Awesome shoes!

Rated 5 out of 5 by from Light Runners I shopped for the best runners for myself and tried a few. I like the light ones. Cushioning is good, but it feels like wearing hills. I picked La Sportiva Helios , because it feels like I have no shoes on, plus it is clearly a quality product. Simply beautiful. :-) I bought a second color after the first pair :-) Works for me.
