Propa Tongue Shim

Propa Tongue Shim The Tongue Shim is a simple, highly effective fix for excess cuff volume, poor shin contact, and harsh pressure points. If your boots feel loose up top, or you’re cranking buckles just to find support. this is the missing link. Positioned bon the outside of the liner tongue, the shim fills dead space and absorbs impact, creating a more even, controlled flex and a stronger connection to the ski. Made from premium EVA foam, it adds comfort without compromising precision, so you can ski harder, longer, and with more confidence. Ideal for: Narrow or low-volume lower legs Packed-out or ageing liners Reducing shin bang and pressure points Improving cuff contact and flex consistency Each shim is backed with high-strength 3M adhesive for a secure, long-lasting hold. A little heat during installation helps activate the bond and ensures a perfect fit. Sold as a pair (2 Tongue Shims).
