Zandstra Ving clap skates have unique long track blades that convert from clap to fixed and back again in seconds, using a removable key. Best of both worlds: Free-heel 'clap' action for rapid acceleration in race conditions. Plus the stability of a fixed blade for recreational skating. Both leather and synthetic boots offer ankle support, but the synthetic boots have the most support. Tool Steel blade, Rockwell 60 hardness. Made in the Netherlands. European sizes 36-47 (US men's 4½-13).
With the warmest, most supportive high-top synthetic boots: $269. With lower-cut leather boots: $339.
