Ex-racers, industry pros and others who value the performance of a plug boot but don't need the torture of getting one to fit anymore can find what they're looking for both performance and comfort-wise in the Nordica Promachine 130 Ski Boots. Solid all polyurethane construction in a slimmed down design, a substantial 3D Cork Fit R liner designed to cradle the heel and drive the ski as well as you are able, and a wide 45mm strap with Power Driver top buckle deliver all the performance you've dreamed about without having to unbuckle every run.
