The Flow Tracer Boa Coiler boots were designed with serious shredders in mind. The Tracer features the Boa Coiler lacing system with Heel-Lock QuickFit Closure to give you the most secure and comfortable fit possible, with the ability to micro-adjust on the fly. A premium 4-Feather Thermo Spot Moldable Liner is custom-molded to your foot, with a Silvadur Antimicrobial Finish and moisture wicking properties to everything fresh and dry. The Asymmetrical Boa Lacing and boot design eliminate pinch zones and increase torsional flex for the most responsive ride. OC-Kush Heel Dampening provides pillow-like softness, virtually eliminating vibrations from high speed chatter. Spaceblanket Insulation works to keep feet toasty warm while the B.F.T.
