Insole pad for footwear

摘要

A insole pad (1; 51) for placement on top of an inner sole of footwear and adapted in use to cover only an area of that inner sole that is substantially smaller than the human footprint. The insole pad (1; 51) includes a relatively thin, sheet-like body that has an upper surface (33) and a lower surface (41) and an outer periphery (25). The lower surface (41) has sticky or adhesive properties, and is interrupted by recessed areas arranged in a pattern (5; 55). The pattern (5; 55) is configured to include a plurality of channels combined to be at least intersecting or joining, so as to define a plurality of differently sized non-recessed lower surface areas. At least a portion of the channels vary in width, while the pattern has a varying density to provide high and low cushioning values in predefined areas A, B, C; G).

主权项

1. An insole pad for placement on top of an inner sole of footwear, the insole pad comprising:
a relatively thin, sheet-like body adapted to cover only a portion of the inner sole that is substantially smaller than a total area of the inner sole, the sheet-like body having an upper surface and a lower surface, wherein the lower surface has sticky or adhesive properties; and a plurality of channels recessed into the lower surface, the plurality of channels intersecting and joining with one another at a plurality of junctions to divide the lower surface into a plurality of differently sized non-recessed lower surface areas within a perimeter formed by the plurality of intersecting and joining channels, wherein a combined area of the non-recessed lower surface areas substantially exceeds a combined area of the lower surface occupied by the plurality of channels; wherein the plurality of channels are varying in width and arranged in a non-uniform pattern to provide high and low cushioning values in predefined areas; wherein a portion of the sheet-like body between the upper surface and the lower surface elastically deforms into the plurality of intersecting and joining channels when the sheet-like body is placed under load.
