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 is a low profile, more anatomical fit for those who demand the lightest weight and most responsive experience.
<10mm drop heel to toe.
Examples: Pursuit series, RECON Trainers, Sky- weight family, XPRT 2.0
TAC FIT is a modern fit with a bit less volume.
10mm-15mm drop heel to toe.
Examples: Taclite family, Ranger, EVO family
PRO FIT is our tried and true ATAC fit, the most generous fit with the highest volume overall.
> 15mm drop heel to toe.
Examples: ATAC family, SPEED 2, Company 2.0
