Abstract: The present invention relates to footwear which has improved shock absorbency due to a cushioning and has superior support due to a rigid or semi-rigid orthotic plate. The orthotic plate may be removably or securably attachable to the upper, and the padding may be removably or securably attachable to the orthotic plate. The cushioning may further may have supporting blades incorporated therein to counteract any undesired deforming characteristics of the cushioning and/or a bottom plate may be securably or removably attachable to the bottom side of the cushioning. The bottom plate may also have gripping elements which are permanently or removably attachable to the plate to compensate for wear, or for a change in activities. Further, the upper may be removably and attachable and interchanged with other types of removably attachable uppers.

Abstract: The present invention relates to footwear which has improved shock absorbency due to cushioning within a two-plate system. The orthotic or upper plate and bottom plate are separated by cushioning. The orthotic plate preferably provides rigid support between heel and metatarsal region. The bottom plate may utilize multiple rigid segments whereby the toe region is flexible. The bottom plate may also have gripping elements which are permanently or removeably attachable to the plate to compensate for wear, or for a change in activities. The cushioning between the upper and bottom plates distributes force produced at individual points on the bottom plate over the entire upper plate, thereby eliminating pressure points on the foot.

Abstract: The specification and drawing figures disclose, describe and claim replaceable heel system for footwear that includes a plurality of heel bodies. The heel bodies are interchangeably and demountably connectable to footwear. A rigid orthotic plate that is positionably insertable in the footwear for distributing forces longitudinally and laterally during use of the footwear. In one aspect, a compressible spring is positionable in the plurality of heel bodies to relieve pain during use of the footwear. In another embodiment opposing pressure connectable and detachable members are provided to demountably connect the heel bodies to the footwear. In an alternative aspect a flared plug and hollow receptacle are provided to demountably connect the heel bodies to the footwear.

The heel bodies are interchangeably and demountably connectable to footwear. In at least one of the embodiments, the plurality of heel bodies is demountably connectable to an integral contoured rigid orthotic plate that is removably insertable in the footwear for distributing forces longitudinally and laterally during use of the footwear. A compressible spring is positionable in the plurality of heel bodies to relieve pain during use of the footwear. In another embodiment opposing pressure connectable and detachable members are provided to demountably connect the heel bodies to the footwear. In an alternative embodiment a flared plug and hollow receptacle are provided to demountably connect the heel bodies to the footwear.

Abstract: The invention relates to an insole for use in footwear, and is comprised of a plurality of sections that are removably or securably attachable to a bottom layer. The sections can be made of different materials to provide different types of support, e.g. rigid or shock absorbing. The sections may also have different surface characteristics, which for example grip a portion of the foot or are slick to enable the toes to move. The insole can be used to at least partially abate and/or prevent foot and related ailments commonly suffered by diabetics and others with pathologic or painful foot conditions. A kit for making an insole is also contemplated wherein a variety of insole sections are provided that have different cushioning or support features and/or different surface characteristics. The user can choose the preferred insole sections and assemble the sections onto the bottom layer, thereby constructing a customized insole.

Abstract: Ventilating footwear provides air circulation under and around the foot. Apertures in the heel and/or sole and/or midsole communicate with an air compartment in the heel and/or sole and/or midsole, and as the wearer strides, the heel and/or sole and/or midsole are compressed, expelling the air from the compartment and into the footwear upper. The top side surface of the sole or midsole may also be provided with a plurality of air channels which direct and circulate air from the compartment around and underneath the wearer's foot. The footwear may also provide shock absorbence and energy return through the compressible heel and/or sole and/or midsole, and may have a rigid or semi-rigid midsole, which provides support, as well as cushioning below the midsole for comfort.

Abstract: A rigid midsole structure for footwear extends from the metatarsal area to a rear-most portion proximate the heel of a wearer. The rigid midsole accepts any form of replaceable undercarriage structure, and includes means for attaching the undercarriage structure to the bottom side of the rigid midsole. The rigid midsole is preferably formed with an upper surface configured to conform with the bottom of a wearer's foot to provide sufficient rigidity and comfort.

Abstract: An athletic shoe includes a spring interposed in its sole providing superior shock absorbance and energy return. The coil spring increases in diameter and is fixed between two spacers, wherein the spacer adjacent the largest diameter end of the spring delimits a space therein. During compression, the smaller end of the spring passes through the larger end and into the space defined by the spacer. The structure maximizes energy return and prevents bottoming out during compression. In an alternate construction, the sole having the spring is removable from the shoe portion such that the shoe portion can be fixed to a plurality of soles. The arrangement can be further revised to accommodate a hoofed foot of an animal. The spring can also be concealed in a hollow heel member of a dress shoe.
