The One.9 Skate shares the same 3D Anaformable CURV composite quarter as the TotalOne NXG.This gives a more comfortable fit, and more responsive skate. A Hydrophobic Clarino leather liner wicks moisture away from your foot, and dries quickly. Lightweight Anaform ankle pads, along with a Form-Fit footbed that has stabilizer grip and CURV composite inserts creats a great, comfortable fit. The tongue is thick, 52 oz, 2 piece felt with an improved high density guard for added protection as well as great comfort and lace bite prevention. The skate is fully heat moldable, to create a true 360 degree fit, for great overall fit and comfort. Featuring TUUK`s Lightspeed 2 Holder with Replacable LS 2.1 Power Runners, a longer runner, designed for more ice contact area to increase power on strides.
