Very happy with these. I took the advice of others saying Merrell size quite small and got an 11.5 (im normally an 11) and at first i thought they were a touch too big but they arent. They fit perfectly. I especially love the wide toe box. I do find the arch support a little on the strong side though.. In a 0mm drop shoe Id prefer a much smaller or none existant arch support to force my feet/ankles to work, but its a minor gripe. All in all, fantastic shoes!
