Even lighter than its name would suggest, the ThirtyTwo Men's UL2 Single Fast Track Snowboard Boot is crafted with an all new Air Frame exoskeleton to give it feather light weight without sacrificing a touch of durability, and wastes zero time lacing up thanks to the Single Fast Track pull lacing system. The stiff flex offers exceptional support for backcountry endeavours, yet still has enough flex for you to get playful all over the mountain. Serving up a true custom fit, the Level 3 Intuition liner comfortably wraps around your foot without pressure points, thanks to its thermo moldable Intuition foam. The Level 3 footbed cushions your feet with every turn, thanks to its dual density heel pod for maximum impact protection. Helping eliminate heel lift, the inner ankle lacing system provides superior heel hold and performance with a simple and easy to use lace lock. The articulating cuff prevents shell distortion when you're flexing the boot throughout the course of the season. Providing high levels of heelside response, the performance backstay improves stiffness when you're laying into carves and spinning off your heelside edge. Plus, the high density Evolution Foam outsole improves cushioning, and is much lighter than rubber to reduce weight without sacrificing grip for you to boot up icy stairways and rocky ridges with ease.
