text: I've had great luck with these shoes, BUT I tried them on in store before ordering and found that I had to order about 1.5 sizes above my typical running shoe. These are a great trail shoe with a minimalist feel (light and flexible, low heel-toe drop, etc.) but maintains enough cushion for me to run ultra distance. I ran a mountainous 50k and had zero issues with them. The only issue I've had was with my first pair. I learned after a long run that I had to trim the sole insert due to rubbing under my arch. Likely, this was not an issue with the shoe itself, but an issue with how my arch sat on the arch. I would highly recommend to those looking for a lightweight, responsive, but sturdy feeling trail shoe. They do tend to split around the crease of the ball of your foot, others have complained about this, but it doesn't affect anything other than cosmetics. They're inexpensive compared to other ultra shoes, so worth it to me.
