These have helped me resolve some knee issues with buckling, fantastic! After paying for an expensive bike fit, I was happy this $10 solution did the trick.

Using multiple varus (orange) shims has made my rides pure joy. It required multiple however I now have no knee hip or ankle pain. Hallelujah

Great for shoes that need internal wedges

Used for over 10 years for my feet. Really help keep my feet happy and supported. Work really well with the Specialized footpads. I use the Orange size and it helps keep my foot from rotating in the shoe. For me, it is a must-have item
