We recommend our CFRT® composites materials for the following footwear components:
Turf Plate - Typically used in turf footwear, the turf plate is used in place of spring steel to limit the extension of the great toe. PMC has developed a very specific material for this application. An added benefit of using CFRT® is, it reduces the amount of heat transferred from the turf to the wearer’s foot.
Shank Plate - The shank plate is located under the midfoot or arch area of the foot as a support. This area of the shoe is often cut-out or sculpted. CFRT® materials are used as a shank buried under the arch (typically in the midsole) or as an exposed torsional enhancement creating a “bridge” between the heel and forefoot. Both applications will reduce the weight of the footwear as typically other materials can be reduced by using the CFRT® technology. The larger the shank plate, the more biomechanical support and the lighter the footwear can be.
Spring Plate or Propulsion Plate - An extension of the shank plate, the spring plate or propulsion plate extends into the forefoot. CFRT® materials have been extended even into the first and second metatarsal for added spring and resiliency. The plate can be engineered to give the desired balance of stiffness vs. compliance while absorbing the impact of the foot striking the ground. For example, when wings are added to the spring plate, it provides added medial/lateral control to the wearer.
Sock Liner or Insole - As an aftermarket improvement or provided as a comfort or performance aspect of the footwear, PMC CFRT® composite materials can be used as a sock liner or insole providing added support just under the foot. Studies have shown using PMC CFRT® composite materials as a sock liner or insole will reduce foot fatigue, improve stability and make the footwear more comfortable. The composite material is thin and light providing support while not taking up too much room in the shoe. The shell can also be heat adjusted for customization
