A rigid sole plate insole made from carbon composite and polypropylene layers. Composite sole plates are supplied as full length insoles in 2.3mm thickness, which are die cut from an unbreakable and lightweight material.
This product is moulded to a cast and then posted or wedged for functional control. Alternatively, when moulded to a surgical shoe it can be used to give rigidity to the sole unit.
The top surface can be prepared before the linings or postings are attached by buffing.
