Designed to keep your heel and midfoot in place, the lacing system and power strap align your foot within the liner.

A flexible toe box conforms to your forefoot, regardless of the width. With your foot secure in place, this toe box design allows for toe movement, keeping your feet warm.

ZipFit toe boxes are insulated with Thinsulate and real merino wool, keeping your toes warmer while still promoting breathability.

Three cork pouches in each liner (located behind the top of the tongue and on either side of the instep) allow you to adjust the cork fill to dial in your perfect fit.

3mm neoprene lines the interior of this ZipFit, adding a nice element of cushioning without sacrificing the performance of your fit.

A rear flex panel and two front flex points give this liner a 50º range of motion for easier uphill travel.
