Good heel hold for most feet but narrow ankles might struggle to feel locked in. Has what you would describe as a deep instep but still gives a more relaxed rider-friendly overall fit.Photon Boa Specification: Dual Zone Boa® Coiler™ with New England Rope ClosureThe tongue mounted H4 Coiler is the top closure point for the boot. Geared at a ratio of 4:1, it quickly tightens the top half of the boot quickly and effortlessly. To tension the bottom half of the boot, the side mounted Coiler has been specifically designed to provide increased leverage to let you dial in the perfect tightness. This Dual Zone system gives you complete independence of the top and bottom halves of the boot, allowing you to almost instantly dial in the perfect fit and flex for whatever terrain you want to ride. TX3 is Boa’s first textile lace specifically designed and engineered for shell closure on snowboard boots, an alternative to the traditional steel lace. TX3 provides a softer, more flexible look similar to the characteristics of traditional lace. However, unlike your standard laces or speed-lace Boa has designed TX3 to be much smaller in diameter to work with the H4 system but still meet the necessary strength requirements for snowboard boots.Imprint™ 3 Liner with Focus Cuff and Hook and Loop ClosureThe Imprint 3 Liners features Burton’s innovative DRYRIDE Heat Cycle™ technology. This breathable inner lining material utilises interwoven thermally activated carbon thread to capture and reflect heat inwards while wicking moisture away from the foot.The Focus Cuff Heel Hold System boosts heel hold by hugging that sweet spot around your ankle. The Focus Cuff sits slightly higher on the ankle than most other heel hold systems giving increased response and control. To dial in the fit even further, the Imprint 3 Liner can be modified around the ankle by the addition of J Bars. These can be attached and detached quickly via the hook and loop fixings reducing heel lift for even the slimmest of feet.The Imprint 3 Liner is constructed from heat mouldable foam. This innovative material forms to the contours of your feet, reducing unwanted pressure points and helping deliver the perfect fitEST Optimised Midsole with ®Vibram Eco Step Outsole EST® goes beyond bindings by optimising the soles on select boots for a more direct connection.
