The unofficial pro model of resort town lurkers and shop girls alike, the Burton Sapphire™ is for those who literally live in their boots. During those midwinter marathons, let your feet live in luxury inside the heat-ready Flex 2 Liner complete with a truer-fitting, calf-caressing Plush Cuff™. The most cushioned boot in the line, its aura of awesomeness includes a Stay-Puft tongue and backstay, huge 270º Airbag, and the NEW Rad Pad for added love when laces are cranked tight.
- 270º Airbag Cushioning: more cushioning and less weight. A 50% larger airbag covers approximately 75% of the midsole for unstoppable impact protection. Flex Spine™ Backstay: Get effortless medial and lateral mobility with ample edge-to-edge support. Articulating Cuff: Allows the upper and lower zones of the boot to flex independently creates fluid forward motion, minimizes shell distortion, and maximizes heel hold and response. Stay-Puft Calf Capsule: Adding an airbag to the upper portion of the Sapphire’s Flex Spine™ backstay cushions your calf as it interacts with the hi-back. Medium Flex Thin Profile 3D® Molded Tongue: Adjusting the profile of the tongue’s thickness controls its flex, enhances its ability to wrap the forefoot, and reduces shell/liner stack-up for improved comfort. NEW Stay-Puft Tongue: Tuck that knee and tweak it with the smoother forward motion and cush comfort of this padded, progressive flexing upper tongue construction. Plush Cuff 1.0 hugs your calf like no other thanks to a combination of medial and lateral neoprene stretch zones and a super soft fur lining. Flex 2 Liner: Therm-ic Heat Pre-Wired, Flex Cuff Heel Hold System, Plush Cuff 1.0, TaiPanel™ Technology, NEW Rad Pad For Lace Comfort, Velcro® Liner Closure, Ultra-Cush Park 2 Footbed with Aegis™ Antimicrobial Coating, and Heat-Moldable. NEW True Fit™ Shell Cuff: This unique shell construction allows the uppermost lace hook to move independently from the rest for improved comfort and a fit that better conforms to a variety of calf shapes and sizes. Crank the laces tight around your forefoot and ankle, then micro-adjust lace tightness at the sweet spot around your calf muscle. NEW Rad Pad For Lace Comfort: Located on the top of your instep, right where the liner laces exert the most pressure, these pre-curved panels keep your feet happy for hours of on-hill action.
