The Velocity Skate NIS Skis by Alpina are light and lively skate skis that anyone can enjoy. The resilient wood core construction provides consistent and predictable performance and a smooth glide. 44mm wide and tapering to 41mm wide in the shovel, these skis are quick in set tracks, offer reduced swing weight and making it easier to release the tip when you're transitioning between strides. A sintered P-Tex 2000 base gives an even efficient glide and is easy to maintain and holds wax well. Bonded NIS plates are designed to accept Rottefella NIS NNN bindings with easy slide-on installation. No drilling or tools required.
