World Cup Sidewinder ski boot liners:

Skier type

The World Cup sidewinder ski boot liners are the culmination of 30 years of design refinement and stand out as Sven Coomer’s choice liners. Many skiers search for the perfect turn. Sven sought to design the optimal ski boot liners that could help skiers achieve the feeling of a perfect carve. In order to transfer maximum energy from the leg into the ski, the World Cup Sidewinder features a medial side with stiffened plastic from the outsole up to the cuff, preventing ankle collapse. These liners are the highest performing ski boot liners in the world for on piste and in the race course. 

Materials

The interior is stitched with the highest quality leather, sourced from the same tannery that supplies Ferrari, so going fast is in these liners’ DNA. For skiers seeking stability and a true to form fit that perfectly reflects the shape of your foot and lower leg, the World Cup Sidewinder ski boot liners are here for you. Heightened sensitivity that comes with the leather interior matched with the stable drive of the sidewinder design make for the best power transfer possible.

Volume

The World Cup Sidewinder liner is pre-packed with a low volume of OMFit self-molding cork composite, specifically designed for normal volume feet in low to mid volume shells. For ski instructors and active racers focusing on every element of the turn, the World Cup Sidewinder ski boot liners will give you a new edge, holding your foot and lower leg in the optimal position for maximal drive and control.

Features on all ZipFit ski boot liners:

  • Neoprene toe box with Thinsulate and merino wool insulation for warm feet
  • Durable microfiber exterior
  • Asymmetrical  tongue and spoiler
  • Three spot fit adjustment ports to add more cork composite
  • Power strap and speed lacing
  • Instep window to relieve pressure and prevent shin bang
  • Stealth honeycomb rubber laminate to reduce vibration

The ZipFit way:

ZipFit was founded by Sven Coomer, a pivotal character in the transition from leather ski boots to the modern plastic ski boot shell. ZipFits are designed to restore the feel and function lost in the transition from handmade leather boots to factory produced plastic shells by offering a custom fit solution — liners that don’t pack out, keep feet in the proper position, and last for seasons to come. We source the highest quality materials and make our ski boot liners by hand in Montebelluna, Italy.

Sven helped pioneer foam injection liners but was frustrated with the “one-and-done” fitting process and the volatile chemicals used in foam injection. ZipFit, which stands for Zero Injection Pressure Fit, offers customers a ready, out of the bag solution that morphs to the anatomy and needs of the skier’s foot. Our liners have three ports where our proprietary cork composite (a sustainable solution with no volatile chemicals) can be added for increased heel hold, ankle comfort, or padding in the tongue.

ZipFit values at work:

All ZipFit ski boot liners work best when used with a quality orthotic footbed. For proper boot fitting, we recommend finding your local certified ZipFit dealer or following the instructions for at home fitting. ZipFit has a money back guarantee if our ski boot liners are not the best solution for your feet. Additionally, if you take care of your liners appropriately but your ZipFits have a defect or show abnormal wear and tear, please contact us, we will take care of you. We want our skiers on the slopes skiing and will be sure to find a solution.

    Each contour of my foot is met for top shelf response and comfort. LOVE these!

  2. Michael M. (verified owner)

    I have worked in the ski industry for 40 years. I have tried countless different boots and liners. I have a very narrow foot. Heal, and ankle area of my foot has never felt secure in a boot. The zipfit liner is definitely the best fit, as well as comfort I have ever felt in a boot.

  3. Christopher Gage

    I have had the good luck to ski in these liners for the past ten seasons. Let me be more specific – I have skied ONE pair of these liners for the past ten seasons! That’s well over 500 ski days in a single liner. These may seem like a steep investment, but when amortized out the value of these liners is a no brainer.

    All that penny pinching talk is to say NOTHING of the technical/performance superiority of my ZipFits. The edge control from the sidewinder is unmatched. My feet stay warm. The cork makes for the most comfortable boot setup I’ve ever skied.

    Not much more to say other than whenever (if-ever) my liners wear down I will be buying another pair with a smile on my face.
