Here's what other sites are saying:
The Alpina Rottefella Touring Combi XC Ski Bindings with NIS Plate are compatible with the NIS system ski. The binding also comes with a two-piece NIS screw-on plate which now allows any flat ski to provide the NIS system advantages. The new Touring Combi is optimized for both classic and skate styles.
