Product Overview
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
- 3/32" (2.3mm) for those who just need a little tightening up.
- 5/32" (3.96mm) for those whose boots are obviously too big, and for most soft snowboard boots.
- 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 a pair

5 Insole boot shim
Posted by Peter G Bradshaw on Apr 08, 2022
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!

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

4 Shoe shims
Posted by Duane Stark on Jun 30, 2021
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.

5 Simple solution
Posted by Kamyar Ilkhanipour on Mar 28, 2021
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.
