Size Chart

ATS are engineered to be worn without socks, but don’t worry, our lining is smooth and soft on the feet and we have removed as much internal stitching as possible to prevent chafing or blisters.
If you prefer to wear socks you might find the first fit to be a little tight, hang in there, after a couple days the memory like materials will naturally form to your feet.
**All measurements are in millimeters. Please refer to our Fitting Guide for instructions on how to correctly measure your feet.**
