Customer Reviews

Comments: Size 10.5 (had to buy a half size smaller) I usually run Salomons size 11. Height 6'0 weight 160 MPW 80 - 110 (ultra runner) So far these shoes have been great. The overall "feel" is stiff and supportive but flexible enough to still have a "grounded" feeling. The toe-box is somewhat wide and the heel is tight but extremely supportive. The outer is breathable and soft, and it really holds the foot well. The shoe has done well on both trail and road (but I prefer trail). Only time will tell how the shoes will perform when they begin to approach the 400 mile mark.
