Abstract: A bumper system for use in a shoe may include one or more elastomeric members having a curved top portion opposite a generally flat bottom portion; an adhesive layer on said bottom portion; and a peel-removable cover of said adhesive layer, wherein the one or more elastomeric members includes a first elastomeric member that is configured to be secured within a toe box of the shoe and is configured to match a foot-toe-gap arc of a user of the shoe. A method of using a bumper system in a shoe is also disclosed.

Abstract: Provided is a shoe heel engagement system and method of using the same to secure a user-heel-shoe interface and prevent unintended slipping and discomfort. The heel engagement system includes an elastomeric molded system having a plurality of projecting bumpers and stress concentration geometry features. The geometry stress concentration features may be linear or curved and may have multiple profiles. The geometry stress concentration features are arranged at least transverse to a heel arrangement, and may optionally be aligned with a heel arrangement and in arcuate form relative to heel or a foot-heel curvature improved security and shoe comfort that allow for easy bending-without buckling to fit the inner shape of a shoe. The geometry stress concentration features allow for easy air flow, moisture flow, and easy installation and adaption to the foot-shoe geometry.
