Top-end performance and construction with a slightly softer flex. The RC4 The CURV GT 115's lightweight shell and low volume fit, plus optional VACUUM molding offer a secure and comfortable fit. Combine this with the adjustable cuff position and this boot can be dialed in for fast, skilled skiers. The lace-up, thermoformable IFZ boot liner, with Primaloft insulation, provides a warm, completely customizable fit. Small, individual fit pads can be attached to the liner to cover specific spots or provide a secure heel fit. The tongue can be removed and ground to better accommodate any lower leg or instep shape. A variable fit boot board plus the option of VACCUUM molding complete the full customizable package. GripWalk adds security, comfort and convenience.
