Abstract
An orthotic or prosthetic spacer element including a ventilated and compressible core having first and second opposed surfaces, and a discrete and continuous web-like silicone-based frictional layer secured to the core first surface. The frictional layer and the core first surface have a plurality of coinciding apertures formed in a pattern. The spacer element may include a foam layer secured to the core second surface such that the foam layer and the core have different rigidities. A layer of hook-receivable material may be directly or indirectly secured to the second core surface.

An orthotic or prosthetic spacer element, comprising:
- a ventilated and compressible core having first and second opposed surfaces;
- a discrete and continuous web-like frictional layer secured to the core first surface, the frictional layer having a plurality of apertures arranged in a pattern.
A ventilated orthotic or prosthetic spacer element, comprising:
- a ventilated and compressible core having first and second opposed surfaces;
- a frictional layer directly secured to and adjacent the core first surface;
- and
- a layer of hook-receivable material secured to the core second surface.
An orthotic or prosthetic spacer element, comprising:
- a ventilated and compressible core having first and second opposed surfaces;
- a discrete and continuous web-like silicone-based frictional layer secured to the core first surface, the frictional layer defining plurality of apertures formed in a pattern;
- a first compressible material layer secured to the core second surface, the first compressible material layer and the core having different rigidities;
- and
- a layer of hook-receivable material secured to the first compressible material layer.
An laminated article having a frictional surface, comprising:
- a ventilated core material having first and second surfaces;
- a first frictional layer including a discrete silicone composition layer laminated to only the first surface of the core material, the frictional layer being molded in a continuous web-like pattern extending over the core material.
