Size 10 true to fit, I have wide forefoot from spending 45 hours per week stuffed into a size 27 Technica Cochise 130 flex ski boot ski patrolling. My 6th toe is killing me, however went on several rides in Sedona with these shoes so far. Very breathable and easy to walk in. Secure clip in, stuff enough sole for proficient pedaling. Wide enough that they don't interfere with 6th toe pain. Five Ten sole supper grippy. I would recommend these. I put an orthopedic foot bed in these and now they feel like slipper's, super light.
