The TOUR WRAP liners are designed to work in most A/T and tele shells. A medium volume wrap style liner provides a stiffer, more responsive fit for advanced skiers who want the best performance on the downhill. The adjustable lace system with Velcro closure, in combination with the soft rear flex panel, provide maximum tourability. Additional 4mm removeable foam insoles accommodate a variety of foot volumes, orthotics and foot beds. The Tour Wrap is a medium volume liner and works best with a shell fit* of One – two fingers (1/2″-1¼”) If your shell is a half size, round down for this model. This model can be worn ‘out of the box’, heat molded with the home fit kit or fit by a professional boot fitter.
