A grounding foot-worn sandal has a sole with an upper foot-supporting surface and a lower ground-engaging surface. A strap extends upwardly over the upper surface of the sole for receiving a portion of a user's foot therein. An elongated conductive strip extends from the upper surface of the sole to the lower surface of the sole, such that the elongated strip simultaneously contacts the ground and a user's foot to provide a conductive path therebetween and ground the user with the earth's surface.

Nonslip shower footwear for preventing slippage in showers includes a first shoe that comprises a sole. The sole has a top layer and a bottom layer, which are mutually coupled along their respective perimeters to define an interior space that comprises a gel. A plurality of grips is coupled to and extends from the bottom layer. The grips are tackified to prevent slippage. A shell is coupled to the perimeter of the top layer. The shell and the sole define an internal space that is complimentary to the foot of the user. An entry is positioned in the shell proximate to a first end of the sole for insertion of the user's foot. A plurality of openings is positioned in the shell for water to flow into and drain from the internal space. The footwear includes a second shoe that is a mirror image of the first shoe.

An insert liner is provided and is configured to be removably received in an inner cavity of a shoe. The elastomeric liner includes: a longitudinal portion: opposing first and second lateral portions; and opposing front and rear portions, wherein the longitudinal, lateral, front, and rear portions define a cavity having an opening configured below the opposing front and rear portions and configured to receive a user's foot; and a fastener coupled to at least the front portion and the rear portion of the liner while being bond free relative to a toe portion of the shoe, the front portion is configured to releasably adhere to the tongue portion to maintain the opening below an upper edge of at least one of the heel portion and the opposing sidewall portions and to define the opening configured to receive the user's foot.

A shoe may include an upper portion constructed from a continuous textile (e.g., a knit textile) that includes an elastic region and a structural region. The elastic region may be positioned about a perimeter of an opening into a cavity configured to receive a wearer's foot, and the elastic region may be configured to secure the shoe to a wearer's foot. The elastic region may have a first elasticity that is greater than a second elasticity of the structural region. In an unworn configuration, the elastic region may cause a tread surface of a sole of the shoe to have a continuous curvature. In a worn configuration, substantially all of an intermediate section of the tread surface may contact a surface on which the shoe is placed. The elastic region may improve the performance of the shoe, including the comfort and durability.
