I bought these for a Spartan Race I am doing this weekend. At first I didn't care for them because the heal of the shoe comes up pretty far, but now that I have broken them in it's less irritating. The tongue of the shoe is too short I feel. When I tie my shoes, the laces and tie are above the tongue. Also, I am flat footed so I need a shoe with no arch support so it works out well for me. Will add another review once I run in the race this weekend to let you know of performance and ability to push at water and such.
