Footwear Fit Guide
TighterLooser
Our boots and shoes feature three distinct fits generally based on the intended use for the boot and its materials and construction. If you’ve worn our ATAC boots you’ve been wearing our most roomy fit and many of our newer boots and shoes feature a lower volume fit. Look for these three icons for a better understanding of how each different collection of boots will fit.
Bio Fit
BIO FIT is a low profile, more anatomical fit for those who demand the lightest weight and most responsive experience.
