The Nitro Select TLS Snowboard Boot offers precise response and all day comfort for riders who prefer a quick reacting, supportive boot. The removable tongue stiffener lets you fine tune the boot's flex to match your riding style, while the advanced TLS 5 Twin lacing system ensures a comfy, secure fit every time. Along with features two speedlace pulls to let you dial in the perfect fit with secure heel hold the new TLS 5 Twin lacing system offers easier lace engagement and release than ever before. If anything breaks it can easily be fixed without special tools, and when you're ready to get out of your boots simply give the Bail Out tab a quick pull and the shell opens without a fuss. An armored spine provides reliable support and a removable Power Tongue Stiffener insert stiffens the boot for backcountry booter sessions, which can be removed for a looser flex when you're lapping the park. A heat moldable Cloud 9 liner allows for a comfy custom fit, and it's been enhanced this season with D30 material for enhanced cushioning. ILS liner lacing provides extra security and prevents heel lift. Air damping in the heel and an EVA midsole cushion harsh impacts from overshot landings and big cliff drops. The Therminator shield in the bottom of the boot's shell reflects heat to keep your feet toasty. The rugged and durable Vibram Icetrek outsole is designed specifically for snowboarding, making short work of icy ridgelines and slippery parking lots.
