How to Measure — Footwear

1
Foot Length Place your foot on a flat surface. Measure from the back of your heel to the tip of your longest toe.
2
Best Time to Measure Measure in the afternoon or evening — feet naturally swell throughout the day for the most accurate fit.
3
Half Sizes If you're between sizes, choose the larger half size, particularly for hiking and trail footwear.
4
Sock Thickness When measuring for hiking or winter boots, wear the type of socks you plan to use — this affects your ideal size.
