Size Guide

OTB Boots are designed to fit true to size when measured using a standard Brannock Device (the silver metal tool used in shoe stores for foot measurements).

Our sizing is similar to many popular running shoe brands, including Hoka, Asics, Brooks, and Altra. For women, we recommend subtracting 1.5 from your running shoe size to find your OTB Boot size (e.g., if you wear a size 8.5 in women’s running shoes, you would be a size 7 in OTB Boots).

If you require a wider fit, we offer WIDE options that correspond to approximately EE+ width.
