It is lower and lighter (less hardware) than traditional boots, with a huge center groove to do your damage with. Fully heat moldable MyFit 2nd Skin Liners (extra velcro piece to adjust stiffness) with lace holes all the way for best support. Top buckle, velcro powerstrap, UC 60mm 88A Wheels and Wicked ABEC9 Bearings.
