The Photon Boa® is designed for those who want comfort and exeptional good fit, combined with the precise Boa® Coiler closure system. Even better, it\'s also available as a version for the Burton Step On® binding - the Photon Step On®. Hard chargers who prefer the response that feels fused to the foot will appreciate the cranked-up power of the Lockdown Lacing. Get the traction required for hiking out of the park and into the backcountry with the Step On® EST® Vibram outsole. Sleeping Bag Reflective Foil reflects heat back to the feet to keep you out on the hill as long as you want. With the Photon Step On® no wishes remain unfulfilled. Outer Boot Get an instantly broken-in feel right out of the box. Total Comfort is an exclusive construction that eliminates the break-in period for a fit that feels just as good from day 1 to 100. All Burton boot tongues feature a snow-proof internal gusset construction to completely seal the lower zone of the boot, keeping feet warm and dry. The Step On® Backstay is optimized for Burton\'s Step On® system and is snugging up the fit between boot and highback. The rubber print backstays also shave weight and enhance material-to-material grip. The result of this printed rubber application is a more direct transfer from boot to binding to board for reduced rider fatigue. The firm flexing 1:1 PowerUP Tongue provides an increased response with great rebound and durability. EST® goes beyond bindings by optimizing the soles on select boots for a more direct connection. Lower-profile, lighter weight, and with a reduced ramp angle, the Step On® EST® Outsole lowers your center of gravity and improves feel. The Vibram EcoStep rubber outsole gives you ultimate grip, in a lighter package and with a 30% recycled construction. All without sacrificing an ounce of cushioning thanks to ultra-dampening B3 Gel inserts. Liner The heat-moldable Imprint™3 Liner with DRYRIDE Heat Cycle™ comes with a Level 2 Molded EVA Footbed with ESS Support Shank and antimicrobial coating. Boosting heel-hold by hugging that sweet spot around your ankle, the Focus Cuff rides slightly higher on your ankle for increased response. Lacing System The Photon Boa® boots feature Dual Zone Boa® System and the virtually indestructible, warrantied for life performance of Burton‑exclusive New England Rope laces. Built with a redesigned inner Coiler spool to route the laces, the dial‑it‑in system retains its quick, easy, and effective lace adjustment. Natural fiber ropes equal a more natural flex and feel for greater all‑day comfort. The dual-zone set‑up quickly loosens or tightens with simple twists of the Boa® dial. Important Sizing Information Match up your bindings and boots. Step On®︎ bindings ARE ONLY compatible with Step On®︎ boots. Do not use either product with non-Step On®︎ boots or non-Step On®︎ bindings. Double check the sizing chart to ensure that you have the right size binding for your boot size. Pairing incompatible size boots and bindings will result in malfunction and could compromise your safety. Also, men\'s and women\'s sizes are gender-specific for a reason. Combining men\'s and women\'s Step On™ products will result in malfunction and could compromise your safety.
