I would have given these 5 stars if they had slightly thicker insoles. Fairly stiff outsole that works well on pavement but really eats up trails. If you spend a lot of time on trails with wet grass or dead, wet leaves, this couldn't be better. Just over 100 miles and they are alive. The Boa system is handy, but not a game changer like I thought. It turns out I don't mind tying my shoelaces.
