Abstract: A running shoe can include a sole and an upper formed separately from and connected to the sole. The sole can include a toe cap connected to a toe portion of the sole, at least one drainage hole positioned at and extending through the toe cap, a drainage hole cover including a flexible water permeable material extending over and visually obscuring the at least one drainage hole, the drainage hole cover extends over an area of the toe cap adjacent to and surrounding the drainage holes, and a foot cavity defined at least in part by an interior surface of the upper.

Abstract: A shoe can include a sole with a top surface and a bottom surface opposite the top surface, an upper member coupled to the top surface of the sole, and a sensor coupled to and surrounded by the sole. The sensor can include a processor an antenna in communication with the processor where the antenna is positioned proximate the bottom surface of the sole.

Abstract: A shoe includes an upper, an outsole, and a midsole. The midsole can be constructed with a plurality of geometric protrusions formed in the upper surface of the midsole, the lower surface of the midsole, or both surfaces. In one embodiment, the protrusions can be substantially triangular in cross-section. A plurality of grooves can separate the protrusions from one another including a first set grooves extending in a longitudinal direction, a second set of grooves extending in a lateral direction, a third set of grooves extending at a positive angle relative to longitudinal direction and a fourth set of grooves extending at a negative angle relative to the longitudinal direction.

Abstract: A running shoe includes an upper, a foot cavity defined in part by the upper and having a foot cavity length starting at a rearmost heel surface and ending at a frontmost toe surface of the foot cavity. The running shoe further includes an outsole including one or more metatarsal lugs, and a midsole. The metatarsal lug is disposed on the outsole under a corresponding metatarsal bone of a user when the user is wearing the running shoe and has a center disposed at a center point corresponding to a location between 65% and 67% of the foot cavity length.

Abstract: A shoe can include a sole, a cavity defined in the sole, and a spring plate disposed within the cavity. The spring plate can include an elongated shape with a central axis where the central axis is aligned with length of the sole and a flat profile in the midfoot region of the sole.

Abstract: A running shoe includes a sole, an upper connected to the sole, a foot cavity defined at least in part by an inside surface of the upper. The sole includes an outsole, a midsole disposed over the outsole, and one or more side reinforcing members incorporated into the midsole, the side reinforcing member including a first portion extending into an interior of the midsole from an outer face of the midsole and a second portion extending along the outer face of the midsole.

Abstract: A running shoe includes an upper, an outsole, a midsole and a stone guard. The stone guard includes a unitary plate member including an aft section and a fore section, wherein the fore section includes a first plurality of portions corresponding in size and location to bones of a human foot including a plurality of phalange portions individually cantilevered relative to the aft section.
