The Madshus Redline Pro Skate, like the entire Race Pro boot series, is based on the reference model Redline Skate and therefore offers a high performance platform. The integrated Power Base reduces weight and improves stability and control, while the slightly roomier last makes this boot a great choice for skiers who find the Redline Skate too narrow. Loops of lace eyelets embed comfortably underneath the visible lacing of the Madshus Redline Skating boot, securely wrapping the entire foot laterally and medially with balanced tension for better heel support and overall fit. The Madshus Redline Pro Skate is covered with a softshell membrane to keep your feet warm and dry.  NNN Compatibility
