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. Quick Cinch Side/Rear Lace. Sock Construction. Option 2 Closure.
