Product details

Looking for a replacement power strap or need some power straps for a different pair of boots?

ZipFit founder and president, Sven Coomer is credited with introducing this critical element of the ski boot, but very few liners come equipped with a power strap. The ski boot liner is what comes in contact with the leg, the shell of the boot itself is inanimate. Placing the power strap around the liner keeps the foot secure and then the buckles of the boot hold the liner in place.



Our power straps come in 3 sizes that vary depending on the size of the liner.

  • Short: ~51cm fit for liners sizes 21.5 – 24.5
  • Medium: ~53cm fit for liners sizes 25.5 – 28.5
  • Long: 56cm fit for liners sizes 28.5 – 31.5
Sold in pairs

95% of the time, the power straps that come with our liners are the right fit for skiers, though occasionally folks with smaller calves of bigger calves need a different size.

Nothing wrong with the power straps but....I am 6' tall with what most people would state as completely average calves and yet, even the long straps are really not long enough (they work). The standard strap (medium) must be made for some boney assed waif like people cause I don't think I could strap it around my upper arm its so small.

After 3 seasons in my Zips (skiing most days), my left liner's power strap kinda gave it up. So I ordered a new set. Easy. Lots of grip on these new ones and I'm good to go. Can't imagine skiing in any other liners/boots at this point. No comparison.

I've easily skied my Zip Fit liners for well over 450 days. I just purchased new ski boots, tossed out the stock liners and put my old Zip Fits in. I replaced the laces and the power straps and now they look new. I re-cooked them and now they feel new. I ordered a small power strap for my 24.5 shell. They work but I wish I would have ordered the medium. Overall a great product that is well worth the premium price. Thank you for YEARS of performance and comfort Zip Fit.!!!

These power straps work great. Make sure you measure your original power strap and follow the revised website sizing and you shouldn’t have a problem. Awesome customer service, as usual from zipfit.

These power straps are well made, solid, brilliant colors and tight weave for maximum strength. On top of that, the company has some great people who will answer your questions right away and take good care of you if you need it. I had a quick question and Jeff from the company Zipfit immediately responded and took care of the problem, fast, no arguing, no fuss, just a quick positive solution and email. Can't go wrong working with or ordering from these guys. Happy Skiing! Aloha, Yumi
