An apparatus includes a heel section, a mid-foot section, and a toe section. The heel section, the mid-foot section, and the toe section collectively have a geometric shape having a first slope of a polarity along an inner edge of the apparatus from the toe section to the heel section and a second slope of the polarity along the inner edge of the apparatus to an outer edge of the apparatus at the toe section.

An athletic training shoe has an outsole and an upper shoe portion. The portion of the outsole adjacent the front foot cavity has a plurality of molded cleats. The portion of the outsole adjacent the heel cavity is arched up and away from the cleat portion. About the circumference of an opening of the upper shoe body are cushioned hemispherical protuberances, acting as an ankle stabilizer for a wearer of the shoe. This ankle stabilizer can be inserted in the shoe upper or integral therewith.

Systems and methods for customizable footwear inserts having a plurality of removable sections. Removable sections may be permanently bonded to adjacent layers of the inserts to eliminate or minimize the tendency of removable sections surrounding the removed sections to fall out or migrate into the cavity created by the removed sections. In some aspects, multiple layers are provided to increase the comfort, support, and/or fit provided to the wearer of the insert. Further, some embodiments include a removable backing that, when removed, exposes an adhesive that may be utilized to, inter alia, adhere an original insole of footwear to the top of the footwear insert such that the user's foot is still in contact with the original insole when wearing the footwear.

A tool for removing orthotic inserts from inside of a shoe. The tool consists of a blade with a narrow tip for inserting between the edge of the orthotic and the inside of the shoe, a housing attached to the blade, the housing internally containing an LED light, a battery, a controller, and an on/off switch to active the light, and a handle use for leverage to remove the orthotic. The handle is covered by a soft pliable rubberized grip made of a silica gel material.

In general, certain embodiments of the present disclosure provide an augmented heel cup protective insert device for shoes. The insert device includes a posterior segment corresponding to the curvature of a heel of a shoe. The device also includes a medial wing, a medial parabolic formation that extends in a direction from top to bottom of the device, an inferior segment, and an angulated segment to meet the beginning of the edge of the heel on the medial side of the shoe.

Provided is a shoe or device for inserting into a shoe, having a shallow channel on a top side of a contoured insole or shoe, specifically under the 1.sup.st metatarsal shaft of the wearer. The shoe also has a rear region or heel cup positioned to underlying a wearer's calcaneal tuberosity, the rear region being shaped to accommodate a planer surface of the wearer's calcaneal tuberosity, an upper surface of said rear region having a raised portion underlying an area of the wearer's calcaneus immediately forward of the wearer's calcaneus tuberosity.

A breathable ergonomic insole for use with a high-heeled shoe includes: an upper layer; an insole body; a plurality of raised support structures, including front, central, and rear support structures; a plurality of perforation assemblies, each comprising a plurality of perforation apertures; front and rear grip patterns; a central grip pattern comprising a plurality of hexagonal indentations, for which a subset is penetrated by a corresponding perforation assembly.

A multi-sided, multi-purpose liner is provided for use in footwear. Each side of the liner provides one or more benefits to the wearer. The liner is reversible, such that a first side with a first benefit can contact the wearer's foot or a second side with a second benefit can contact the wearer's foot. The wearer can flip or rotate the liner so that the side having the desired benefit contacts their foot during use. One side of the liner may include a plurality of benefits in a preselected pattern across the surface. A liner kit provides a material blank from which the liner may be cut to produce a desired distribution of benefits. The benefits of the liner may vary with respect to the location on the surface of the liner, with some areas of the liner displaying an increased or decreased degree of a specific benefit.
