Claims6
In combination:
- footwear having a heel portion, a toe portion and an arch portion between said heel portion and toe portion, said footwear having a bottom surface defined by said portions;
- an orthopedic support having a flat bottom and a generally uniform thickness when in an unstressed condition, said orthopedic support including a layer of cushioning material attached to said footwear bottom surface at said arch portion, a layer of adhesive, and a layer of strong, abrasion-resistant material, said cushioning material being laminated to and sandwiched between said adhesive layer and said layer of strong, abrasive-resistant material, and said adhesive layer securing said orthopedic support to said footwear bottom surface, said orthopedic support having a front end, a rear end, and opposed sides extending between said front end, a rear end, and opposed sides extending between said front and rear ends and generally conforming in shape to opposed sides of said arch portion, said orthopedic support being substantially confined to the area of said arch portion whereby virtually all of the support for a wearer's foot is provided by said arch portion when said wearer steps on said footwear with said orthopedic support positioned on a support surface, said abrasion-resistant material engaging said support surface when the wearer steps on said footwear and said orthopedic support supports said wearer's foot and operable when either in said unstressed condition or in a stressed condition when said cushioning material is compressed when a wearer steps on said footwear to maintain said footwear above and out of engagement with said support surface when the bottom of the wearer's foot is substantially parallel to the support surface, said cushioning material being non-uniformly compressed along the length thereof when the bottom of the wearer's foot tilts relative to said support surface when said wearer takes a step, and said orthopedic support exerting an upwardly directed force against the wearer's foot having a maximum force location which moves generally forward from the vicinity of the rear end of the orthopedic support to the front end thereof as the foot tilts from heel-down to heel-up position to exert a massaging action on the bottom of the wearer's foot which stimulates the circulation of blood therein.
A method of promoting blood circulation in a wearer's foot while said foot is enclosed in footwear having an arch portion, comprising the steps of:
- applying an orthopedic support including a layer of cushioning material to said arch portion;
- confining said orthopedic support to said arch portion;
- walking on a support surface;
- during said walking, maintaining the heel and toe portions of said footwear substantially out of engagement with said support surface;
- and
- while said orthopedic support engages said support surface during walking, exerting a continuously variable massaging force on the arch portion of the wearer's foot.
