Abstract
An arch support device has a lower layer of a semi-rigid material shaped to conform to the arch of a wearer's foot and to provide an arch supporting function when inserted in a shoe, a second layer of cushioning material such as foam secured to the upper face of the lower layer; and a third, cover layer of pliable material secured over the second layer. At least one of the lower and foam layers is of variable thickness.
Claims9
An arch support device, comprising:
- a first, lower layer of semi-rigid material shaped to conform to the arch of a wearer's foot and to provide an arch supporting function when inserted in a shoe, the lower layer having a lower face for facing the sole of an item of footwear, an upper face, a heel region at one end, an arch region, and a toe region;
- a second layer of cushioning material secured to the upper face of the lower layer;
- a third, cover layer of pliable material secured over the second layer;
- the lower layer being of variable thickness;
- and
- the upper face of the lower layer being contoured to follow the general contours of at least part of the sole of a wearer's foot, having a generally concave area at the heel region and a convex, raised area extending from the arch region towards the toe region for engaging in a groove of a wearer's toes, the convex, raised area having a thickness greater than the thickness at the heel or arch region.
