Skier type

The World Cup sidewinders 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.


The interior has a neoprene tongue and the rest 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 Sidewinders 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.


The World Cup Sidewinder liner is pre-packed with a moderate 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.

    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.

    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.

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