The Zandstra Ving Long Track III Klapschaats 3550 is a long-track clap skate built for speed skaters aiming to get the most out of every stride. Its clap mechanism lets the blade stay on the ice longer during each push, supporting a smoother, more efficient glide.

The blade is made of rust-resistant stainless steel with a 60 Rc hardness rating, so it stays sharp even after repeated sessions in varied ice conditions. With a 25 m radius curvature, it balances stability at high speed and controlled turning, helping skaters carry momentum through each lap.

The 25 m radius describes how gently the blade curves: a larger radius gives more stability but wider turns, while a smaller radius would allow tighter cornering. The Rockwell C hardness scale (Rc) measures steel’s resistance to wear and deformation; at 60 Rc this blade remains rigid and keeps its edge longer, reducing the need for frequent sharpening.
