The 2025 Nitro Cave TLS Step On boot is the perfect collaboration between two powerhouse snowboard brands, combining the best fitting, most comfortable snowboard boot and the most convenient binding interface system on the market. Once you try this boot on you question how you ever wore any other boot before this one, with its TLS lacing, comfortable and responsive Cloud 9 liner, and interchangeable stiffness, the Cave TLS really speaks for itself in terms of comfort and technology. When one of the best fitting, most responsive boots on the market is coupled with the intuitive Burton Step On system, you know you get a boot which is a match made in heaven will not let you down any day of the season.
Boot Type: Advanced All Mountain
Boot Flex (1 = Soft / 10 = Stiff): 8/10
Lacing System: TLS 5 Twin Lacing System
The Nitro TLS 5 Twin Lacing System is one of the best speed lace systems on the market, with easy lace engagement and release, along with low abrasion Dyneema laces for long-lasting, reliable performance. TLS 5 features two independent upper and lower lacing zones, so you can lock in your ideal fit in a flash, adjust your lacing without needing to step out of your bindings, and bail out of your boots in record time at the end of the day.
Liner: Cloud 9 Liner
The Nitro Cloud 9 Liner is one of the best liners from Nitro, with a lightweight, supportive fit that will blow almost any other liner out of the water. All Nitro liners are heat mouldable, and while it isn't necessary, a heat mold can give you a more custom fit from day 1 as opposed to wearing the boot in. The Cloud 9 Liner comes with a triple-density Ortholite Footbed, which offers superior shock absorption and energy return with minimal compression, so your footbed will perform consistently for the entire life of your boot. It is also quick-drying, extremely lightweight, and has an anti-microbial coating, making your boots smell better, feel better, and last longer.
ILS Liner Lacing
The Nitro ILS Liner Lacing system features a lacing harness directly connected to the boot shell that snugly wraps around the liner, firmly securing it in the shell for strong hold and a precise fit.
Re/Lace Liner Locker
The Re/Lace Liner Locker revolutionizes how a liner lace functions. During a day of snowboarding, your boots are going to loosen. Your foot settles, your boot expands, it happens. With the Re/Lace Liner Locker, once the laces are locked in at the start of the day all you need to do is pull the liner lace tab to retighten your liner, without ever needing to undo your boots.
Therminator Shield
The Therminator Shield is a thin thermal layer between sole and liner that reflects heat back into your boot, keeping your feet warm all day.
Cushioning / Traction: Ortholite High Cup Dual Density Footbed with Nitro Step On Outsole
The High Cup Dual Density Ortholite Footbed is created with excellent levels of shock absorption and energy return. It also has a unique open cell structure that wicks moisture away, dries quickly, and contains a patented anti-microbial formulation to fight fungus, bacteria and odour. This lightweight technology provides optimum performance without adding excess weight to the boot. The EVA Midsole reduces overall weight and provides cushioning and insulation and the Burton Step On Rubber Sole has an effective traction pattern, with an abrasion resistant, grippy rubber sole that provides durability, grip and insulation.
Shell: Ankle Strap with BOA
This new ankle strap with BOA is designed to fit the boot shape and provide the support feel of a binding ankle strap. It offers extra heel hold and ankle support.
Power Tongue Stiffener
This removable piece adjusts the stiffness of your tongue, and in turn, the response of your boot. Add it in for more aggressive turns and quicker response, or take it out for a little more freedom and a more relaxed ride.
