Be warned! These are great sandals, but they need to be worked in. Don't think that you can take these on a trip without working them in. They sprained my big toe the first day, but once you work them in they are great sandals. You will need to wear them at least two hours a day for about two weeks. If you don't the sandal acts like a noose on your big toes. Once you have done that, they will quit hurting your big toes.

Like others said, the toe loop likes to tighen itself on your big toe, but it seems like it's doing that less and less as I wear them in. I've worn them about 8 hours a day (or more) for day to day use since the day I got them, no blisters or anything. Haven't tried them on the trails yet, but plan to next weekend. The stealth is great, but loses a lot of its stick once it's a little dusty.

I usually wear 12-13 shoes. I ordered a 12 and probably could have gone with an 11.

These are great sandals with the grippier soles and the double straps provide a more secure fit. However, the toe loop seems to tighten itself, so it has to be readjusted every few days. They're great from river to city to desert and canyons. Great for scrambles too.
