Sock and a method of knitting a sock

A double-layer sock comprising an external layer positioned over an internal layer, the double-layer cushioned sock is produced by:

• providing a tubular fabric shaped from a first end to a second end as the external layer continuing to the internal layer, wherein the internal layer has a shape that is a mirror shape of the external layer reflected about a center line of the tubular fabric,
• permanently attaching a first cushion patch to either the external layer or the internal layer part of the tubular fabric, wherein the first cushion patch is made from a polymer in a honeycomb pattern, wherein the first cushion patch is configured to deform and stretch along with the fabric of the sock,
• folding and drawing the external layer completely over the internal layer to invert thereof such that an exterior surface of the external layer becomes an interior surface covering entirely an exterior surface of the internal layer, wherein the first cushion patch is encased between the external layer and the internal layer, thereby the tubular fabric forms the double-layer sock, and
• attaching the first end to the second end.
