Description
- This application claims priority to, and incorporates by reference, for any purpose, the entire disclosures of, U.S. Provisional Patent Application No. 61/541,337, filed Sep. 30, 2011.
- The present invention relates generally to footwear and more particularly, but not by way of limitation, to shoe covers with foam cushions therein.
- Many industries such as, for example, the medical industry and semiconductor manufacturing require sterile working environments. Sterile working environments often require that outside shoes be covered by shoe covers to prevent infiltration of contaminants into the sterile working environment. In addition, many non-sterile working environments also frequently use shoe covers. For example, shoe coverings are frequently used in janitorial and contractor professions as a way to protect a worker's shoes. Shoe covers often include a thin layer of flexible material such as, for example, vinyl or plastic that forms an envelope into which an outside shoe is inserted. The outside shoe is substantially covered by the shoe cover. The shoe cover is typically held in place by an elastic band disposed near an ankle region of a wearer.
- Of particular concern in many working environments where shoe coverings are typically worn is that workers are often standing for many hours. Prolonged standing has been shown to cause discomfort in a worker's feet, legs, and back. Such discomfort can lead to compromised concentration and a loss of accuracy or productivity. This can be of particular importance in, for example, operating-room environments where total concentration and accuracy of a surgeon is critical to successful completion of a procedure. In many working environments, a common solution is to place cushioned pads in work areas and other regions with large amounts of foot traffic. However, cushioned pads are often difficult to move making them ineffective in environments where a worker is not confined to a specific location. This is frequently the case in the janitorial and contractor industries. Furthermore, cushioned pads often absorb and hold contaminants and are often difficult to clean making them impractical for many working environments.
- In one aspect, the present invention relates to a shoe-cover system. The shoe-cover system includes a flexible shoe cover sized to substantially envelope an outside shoe and a cushion member disposed within, and along a bottom aspect of the shoe cover. The cushion member is sized to receive the outside shoe. The shoe cover secures the cusion member to the outside shoe and the cushion member is isolated from contaminants by the shoe cover. The cushion member reduces discomfort in a wearer's feet.
- In another aspect, the present invention relates to a cushion member for use with an outside shoe. The cushion member includes a raised lip disposed about a perimeter. The raised lip defines an internal cavity and the internal cavity is sized to receive the outside shoe. A first knurled surface is disposed along a bottom surface of the internal cavity. The first knurled surface provides frictional engagement between the cushion member and the outside shoe. A second knurled surface is disposed along a bottom of the cushion member. The cushion member is generally symmetrical about a medial axis.
- In another aspect, the present invention relates to a method of increasing comfort while standing. The method includes providing a shoe cover and forming a cushion member with a raised lip that defines an internal cavity. A first knurled surface is disposed on a bottom surface of the internal cavity and a second knurled surface is disposed along a bottom of the cushion member. The cushion member is generally symmetrical about a medial axis. The method further includes inserting the cushion member into the shoe cover such that the cushion member is completely contained within the shoe cover and inserting an outside shoe into the shoe cover such that the outside shoe engages the cushion member.
