Nordic skates compatible with Rottefella or Salomon Screw-in bindings! Reuse your ski boots to go skating on frozen ponds, canals, or ovals. The Tango model comes with the hardware needed to mount Rottefella or Salomon screw-in bindings. This means you can grab your cross-country ski boots (boots for skate technique with ankle support) and hit the rinks. Your heel is unattached to the blade, allowing you to extend your push further and get the `clap skate feel`. Surprisingly easy to get the hang of using. Cornering and skidding is fun on these if skating in a straight line becomes dull. Scoop up a pair, keep an eye on the status of pond ice, and enjoy another outdoor winter hobby! Bindings are attached with a combination of self-tapping screws and bolts. The binding position is fixed on the blade and cannot be adjusted. The pre-mounted version comes with Rottefella Sport Screw NNN bindings. NNN-BC or 75mm bindings are purchased separately.
