The Proof boot focuses on the use of lace zones and less overlay material to provide the most mobility in any of our pro-model boots. This boot blends support and lateral movement in a lightweight package. The Proof boot has all the locked-down feel you will need for a cab 900, with the freedom required for a smooth, poked out. frontside indy. Stainless steel eyelets make for an easy transitioned adjustment. A rider can remove the bottom guide, cinch it as tight as they want, and instantly lock it back into place for a one-time modification. This eliminates half the work, as a rider can now just use the rear top lace guides to get in and out of the boot. SIZES: Xsm, Sm, Mini md, Md, Md/Lg, Lg, Xl, XXl Features: ?
