About Cast Freetour AFD
Sold in pairs.
At least 1 pair of AFD will be required per setup. How to select the right AFD:
Will fit all alpine boots that meet ISO 5355. This includes boots that have CAST's tech conversion.
GripWalk compatible AFDs
Will fit all boots with LO GripWalk soles. Due to the limited overlap between Alpine and GripWalk geometry, we chose to design these AFDS to create maximum energy transfer and more consistent function specifically for the GripWalk norm, as a result, they will not work with Alpine boots.
Touring ISO 9523 AFDs
Accommodate boots that meet ISO 9523 touring boot standard. However, the release and retention characteristics of these boots will be affected by the boot’s sole material and tread pattern. They will also fit WTR Boots will fit (Walk to Ride boots),
