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 Helped with heel slippage
Posted by Chelsey on Oct 30, 2018
Helped a great deal with my heels slipping in my minimalist boots. They're Belleville Mini-Mils 102 and very high volume. **Recommended to order one full size larger than your shoe size for proper trim and fit.

5 Bontex insole shims
Posted by Albert on Oct 07, 2018
This is only place I can find this product. After knee replacement, one leg may be longer than the other. Shims make it possible to test different thicknesses inside shoe or boot before deciding to add a permanent shim to the outer sole. Excellent quality. I am fortunate to have come across them in Tognar’s extensive catalog.

5 Don't leave home without it
Posted by Bruno on Mar 10, 2018
I always take a few extras with me on hut trips. You will be someone's new best friend when their new liners pack out mid-week. Turns out the last time in Canada it was a seasoned BC ski guide with a new pair of Atomics. Made his day/week when I dug a pair out of my pack.

2 Works good but black mold grows
Posted by Ken on Mar 13, 2017
I'm not as careful about fully drying my boots as I should be, but these insoles, which do a good job for my fit, grow black mold after a period of time. Partly my fault, partly the fiber material Bontex uses.

5 Work great
Posted by eok on Mar 13, 2016
After my boots' fit has loosened up after a couple seasons, I add these (1/16" version) to reduce volume & firm-up the fit. After some trimming for fit, I install them inside the boot on under the boot liner & fix in place with double-sided carpet tape. These shims also help make my boots a bit warmer. The shim material is fairly dense, so I don't notice any significant impact on snow feel through the bottom of boot.
