Boot Conversion

CAST Boot Conversion allows you to keep rocking the alpine boots you know and love, while adding tech compatibility for super efficient touring.  If you have replaceable soles we will modify those soles and your boots for tech compatibility.  If you have a hard soled boot, we throw on custom rubber tread lifters for better grip and protection. This means you won’t have to replace your boots just cause the soles start wearing thin.  ISO 5355 norm, for alpine bindings, is maintained so they will test and function properly in all your alpine bindings.

Please note that if you have replaceable soles, make sure they are new before sending your boots in.  You do not want to modify worn down toes and heels.  We only modify Alpine (ISO 5355) toes and heels.  We can not modify GripWalk soles except for on the Tecnica Mach 1.

NEW:  We now offer our conversion with Gripwalk or Alpine soles for hard soled boots and the Tecnica Mach 1.  All other boots we still offer the Alpine sole option.

We are done with Boot Conversions for the 20/21 Winter.  Please email us [email protected],  as we will still do some conversions on special request.
