Dynafit Heel Spacers 3mm, 4mm, & 5.5mm

Backcountry bindings need a heel gap to accommodate flex on the rear binding pins when touring. When you adjust the bindings to a new boot it's important you have the right spacing for the binding. Most bindings are based on the Dynafit patent and need 3mm, 4mm or 5.5mm gaps. This design gives you a shim that you can use to ensure you have the right spacing without needing to guess.
