Toe Shims

Our toe shims allow you to reduce the delta angle between your toe and heel piece. While these shims were made with Dynafit bindings in mind, they will work with most Tech bindings. We have three different thicknesses of toe shims. The 1/8"(3.2mm) and 3/16"(4.7mm) shims are laser cut. The 1/4"(6.4mm) shims are either Laser or machine cut. For each thickness there are different versions. Radical FT/ST version is specific to Dynafit Radical FT and ST (non pivot toe) model bindings. The classic version is compatible with a wide range of tech bindings. Look at the charts below to get an idea of the variations in delta angle between different bindings. Dynafit ST & FT 2.0 (2015), Marker Kingpin, G3 ION specific versions now available below.

Note: All measurements are for comparison purposes only. Height is measured from the pins, not from the boot sole.

Our shims do not come with screws.

The 19mm screws are for use with Dynafit Radical Speed, Race versions, and Plum bindings. These screws when used with Dynafit Radical FT/ST bindings and 1/8" shims give about 5mm of bite into the ski which may be suficient.

The 28mm screws are for use with Dynafit Radical FT/ST, and Comfort/Vertical bindings.
