I did size up 1/2 of size since there was no wide width available. Let me tell you, these are them! Just the classic Crocs ( im debating to keep it or not as they are almost equal to the ZSX), ,,, Tin T3,, Good Bass, Great Mids,, Great Highs,( and with IFI DSD Hardware Xbass turn on. Completely healed my hip issue. It was better than I expected I feel so comfortable in it and my posture is AMAZING! Maybe this works when towing a trailer but with a bike rack there is too much play between the hitch extension and the autos hitch. Like two weeks! Other than that they are gorgeous! Buying two more for the other doors.
