Backstay: The back of this boot is reinforced for strength and stiffness. It gives you the support you need for any ability level.
High-Density Rubber Outsole: rubber liner of this boot is extremely durable and dense for digging into the snow without slipping.
PL Liner: The entry level liner, best suited for beginner to intermediate levels. The locking lace up system ensures a good fit with adequate support for riding at slow to average speeds.
PVC/EVA shell/tongue materials: Scientific blend (PVC and EVA are both abbreviations of longer chemical names) offers more durability and comfort than other, uh, less scientific materials.
PVC Upper: The upper of this boot is a flexible PVC plastic, that feels about like a stiff leather. This material is highly waterproof and resists abuse well.
Soft Touch Laces: Softer material used so your hands and fingers don't get torn up while tightening the laces.
Steel Hardware: The eyelets and other critical parts of the lacing system are made of steel for increased wear.
