The DELTA SKATING is a high-performance skate ski designed for competitive athletes to expert skiers. The new thinner core profile is lighterweight, delivering a softer, more user-friendly flex at the tip and tail. Featuring Active Cap construction, Honeycomb core and Extended Edge technology, the lightweight Delta Course Skating ski delivers powerful and precise performance. A lower, shorter tip lightens swing weight and improves maneuverability while the Double Groove Guide enhances stability and tracking. The Delta Skating uses fiberglass laminate instead of carbon for a softer, more accessible flex. NIS Compatible.
