An article of footwear including an upper and a sole. The upper includes at least two supports where each of the supports includes an end and the sole includes a top surface, a bottom surface and at least two slots extending from the top surface to the bottom surface, where the bottom surface includes a channel. A securing member is attached to each of the ends of the supports and inserted in the channel for securing the upper to the sole.

An abrasive insole and method of manufacture. The insole is integrated into the shoe at the time of manufacture. The insole provides a roughly textured surface to abrade the skin on the soles of the feet for purposes of cosmetic appeal and skin health. The abrasive insole works similarly to the textured, sandpaper-like tools that are used in pedicure to soften the skin of the foot by exfoliation. The method of manufacture involves a mold of a sand-and-polymer mixture to produce a flexible insole; one iteration is of 3/32 to 0.25-inch thickness.

A sandal strap reinforcement apparatus which is incorporated into a sandal having a multi-hardness midsole to reinforce the opening around the straps. The apparatus may be made of a molded material, fabric, tape, an o-ring, cord, or the same material as the harder layer. The apparatus is molded into the midsole and serves to protect the hole or slot from damage from a strap inserted through the hole or slot.

Footwear that includes an interdigital boss that is positioned on the footwear and extends upward from a sole of the footwear in a configuration and orientation that is more anatomically correct than an improperly positioned digit of a wearer of the footwear so as to provide corrective forces on the wearer's foot that prevent bunions from forming on the wearer's foot.

A medical shoe having an overmolding layer with a non-uniform density is provided. The medical shoe may include a midsole configured to support a foot, and a frame surrounding the midsole. The midsole may include a foot receiving portion forming a substantially planar surface for supporting the foot and a frame receiving portion opposite the foot receiving portion. The frame may include an overmolding layer extending from a side of the frame opposite the midsole so as to form a ground contacting surface. The overmolding layer may have a non-uniform density. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.

A footwear device is provided having a deformable heel contact member. The heel contact member extends above a top portion of the footwear's sole and deforms into a cavity formed in the sole when the user's heel applies a force against the heel contact member. The heel contact member is resilient and returns to its original shape when the force against the heel contact member is eliminated. The heel contact member is particularly well suited to reduce heel slap of open heeled footwear.

An article of footwear includes an upper and a midsole coupled with the upper. The midsole includes at least a portion of a solid resilin material comprising a cross-linked recombinant resilin and a polar nonaqueous solvent.

This disclosure represents a novel article of footwear that has a built-in toe drying system. The footwear is preferably in the form of a sandal having a sole and a strap attached to opposite sides of the sole and fastened to the top of the sole near forefoot region. More specifically, the footwear has a pair of micro fans releasably mounted in openings disposed in the strap. One micro fan is connected to a duct integrated in strap and the other micro fan is connected to a duct positioned along the side of the sole. The airflow generated by the micro fans are directed towards respective connected ducts such that the airflow is expelled through holes to dry moisture and water on foot of a wearer of the footwear. The sole has a plurality of ripples on top surface thereof and the ripples facilitate drainage of water.

The three invention's utility designs can be used for all types of footwear, including slippers and sandals for indoors, outdoors, SPA, hotel slippers and etc. The first core invention are removable and washable insoles/socks that are pulled over/attached to the base/hard insole of slippers with options when upper parts are also detachable. The second invention is the closed-toes slippers with ventilation holes both on the cloth insole and upper part with option to have it combined with the first invention. The third invention's distinction is the giant size of slippers that are worn over the outdoor footwear that can also have options with the removable sock or ventilation holes from inventions mentioned earlier. There are different details variations described in specifications for all three interrelated inventions. These slippers provide more hygiene, can be worn longer, which is more economical for households and reduces waste produced by slippers.
