Used by World Cup Athletes, the Atomic Prolink Race Classic Binding is designed to get you moving out on the track. Its 2 rail binding construction delivers an exceptional snow feel that is a result of a direct connection between the boot and the ski. This creates a natural feeling in the kick and awesome acceleration. Whats better, the bindings are compatible with all two rail boots on the market so you can slip into your favorite shoes and go for a ski with a smooth kick and glide.
