P-K material is commonly used in the athletic shoe industry having been initially used in garments. P-K fabrics were an innovation from the 1920’s and first used in athletic wear, particularly in the original tennis and polo shirts. The extraordinary comfort of this famous knit means it is still used extensively in the shoe industry to this day. The weave is strong and allows for better fabric breathability. In the Footbionics range we have introduced a stronger grade than is typically used in athletic shoe sockliners. We have chosen this material for several of our more active models including the “Dual Density” and “Professional”.
Another extensively used material in the athletic shoe industry this fabric has a wonderful feel. It’s not as breathable as P-K however it is very durable. Its smooth fleecy feel makes it one of the most comfortable fabrics available. Brushed nylon provides a nice finish and is preferred in stockings or “no socks” shoe use. We have used this on our more cushioned models including the Footbionics “Cushion” and “Supercushion”. For more sensitive feet this material is perfect.
The properties of leather are generally well known. Leather is tough, durable, breathable and very comfortable. Although expensive leather is the material of choice in most dress shoes given that these are worn for many hours each day. Footbionics are one of the very few orthotic companies that produce a "true" leather covered orthotic model. Leather covered orthotics are wonderful to wear and do not draw your feet like other foams.
