Product Description
Ski or snowboard boots too big? These insole shims are the simplest way to take up extra volume. Simply insert the shim between the boot shell and liner (not inside the liner) and the extra volume will disappear. If unsure size up, you can easily trim them to fit (see shim lengths below). Available in two thicknesses.
- Light, flexible, durable and resistant to compression.
- Their non-woven, resin saturated, polyester composition provides additional insulation and resists mildew
- 1/16" (1.5mm) for those who just need a little tightening up.
- 5/32" (3.96mm) for those whose boots are obviously too big, and for all snowboarders.
- Sizes are based on men's street shoe size, we recommend sizing up one size and trimming as needed (see shim lengths below).
- Actual shim color may vary.
- Sold in pairs (one right, one left)

Ski boot insole shims from Wintersteiger.
Having spent "many" years in the ski industry as a boot fitter, tuner, and tech, I can highly recommend these as a great option for taking up volume, and increasing ski bail (Buckle) tension if these are what is required. They will raise the entire liner, if installed properly, and help with a boot that is either slightly, or a-bit-too-big in the heel, instep, and toe. Bear in mind that these should be used as an option "after" a qualified boot fitter has evaluated your fit, and if you have moldable liners, i.e. Intuition, or the likes, it's a good idea to remold the liner so the entire interior is properly contoured. Enjoy a great product, ski well !. ADL

great insole shims
hard to find anywhere else. cheap way to take up a little volume in boot (the thicker version is likely the best bet there, the thinner one isn't very noticeable). Definitely buy 1 size larger than your boot size (as recommended)

Good for Packed Out Boot Liners
these worked perfectly in my 2 year old Lange Rx 120 LV's which have packed out over the last 2 years of 40+ days of skiing per year...

Insole boot shim
These are critical for a good fit. I have one foot a bit smaller than the other and can take up space w/a thin shim in one boot and thicker in the other boot. Custom fit!

Good - but buy 1 size larger
As suggested, buy 1 size longer than needed and trim if necessary. I didn't take their advice, but wish I had.

Shoe shims
I bought these to go into my favorite running shoes. The volume of the shoe is a bit big where I would have to pull the laces very tight to get a good fit. I put these in to take up some of the volume and it worked great, the fit is much better. Time will tell how well they hold up with the flexing so because of the unknown I give 4 stars.

Simple solution
Scarpa Maestrales Fitting a little bit sloppy. Don’t wanna get a whole new liner. These are the ticket. Cut it out to fit and put it under your liner and it’s soaks up the volume without affecting the performance. Five stars.
