Asymmetrical
Cause your legs are different.

The ZipFit tongue is built to reflect the asymmetry in the shape of the lower leg, with more padding on the medial side along the tibia and less padding on the lateral muscle of the shin. The pull tab should be centered on the leg for the tongue to be in the proper position.

Triple insulation
Thinsulate, merino wool, and neoprene.

The neoprene toe box offers a sock-like fit that conforms to the width of the skier’s feet. The toe-box is lined with Thinsulate and merino wool to keep toes toast warm.

Power strap
Power transfer like a Ram 3500.

One of Sven’s earliest contributions to ski boots, the power strap has been widely imitated through the ski industry. The ZipFit power strap helps secure the liner and tongue contact to the shin and can help take up volume for skiers with skinnier legs. Use the power strap for added contact and stiffness, or remove if desired.

Instep window
Instep pain sucks, we get it.

The asymmetrical tongue design includes a cutout of the plastic tongue shield over the instep to accommodate sensitivity common in this area. Neoprene and the cork pouch are the two materials over the foot, so more cork can be added to take up space if needed.

Speed cinch laces
Locked in fit. 🔒

Designed to keep your heel and mid foot in place, the lacing system positions your foot properly within the liner.

1mm ultra thin laces with speed lock lace mechanism.

Cork pouches
Customize your fit where it matters.

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.

OMFit cork composite is the “active ingredient” in ZipFits, both because it remains dynamic and because it is the ingredient that heals the ailment of bad ski boot liners. It doesn’t compress or pack out, it does move around so you can add more if needed.

Neoprene lining
Cushioned confidence or locked in comfort? Yes.

3mm of neoprene lining offer cushion and comfort while still highlighting the efficacy of the cork filling. Feet properly positioned and locked in place.The neoprene interior offers an easier skier experience both putting on and taking off ZipFits.
