If you focus on fit and comfort with the groundbreaking speed of the Step On® Interface, you should start the result of collaboration between two of the most innovative snowboard companies - the Cave TLS Step On® Boot. Nitro leads the way with the TLS lacing system: two independent cutting zones that are quickly tightened and securely locked by a compact and lightweight mechanism that has proven to be reliable in tens of thousands of days on the mountain. Specially designed, abrasion-resistant Dyneema® laces, easy-access handle pockets and our bail-out system for effortless loosening of laces complete the most advanced double lacing system on the market. Nitro's new ankle strap with BOA® is precisely matched to the shape of the shoe, providing the same support and feel as our binding straps. This new feature provides heel support and ankle support.
