A sole board for an article of footwear includes a plate that has a forefoot region, a midfoot region, and a heel region. The sole board includes a channel disposed in a top surface of the plate in the forefoot region. The channel extends from a lateral edge of the plate to a medial edge of the plate. A characteristic of the channel at the lateral and medial edges of the plate is different than the characteristic of the channel at a middle of the channel.

The present invention provides a granular material for a fused deposition three-dimensional printer that enables a flexible molded object to be manufactured with high precision. According to the present invention, provided is a granular material for a fused deposition three-dimensional printer. The granular material is formed of a thermoplastic elastomer, and thermoplastic elastomer has a Shore A hardness of 0 to 10 and a melt flow rate of 10 to 200 g/10 min at least one of measurement temperatures of 120 to 230° C.

An insole for offloading injuries on an area of a plantar surface of a patient's foot includes a body having a shape corresponding to the plantar surface of the patient's foot including a top surface and a bottom surface; and at least one supportive, deformable, deflatable bubble chamber. The at least one bubble chamber extends from the top surface of the body. The at least one bubble chamber is configured to be deflated to relieve pressure on the plantar surface of the patient's foot. A kit including the insole and an article of footwear including a sole, an upper connected about a periphery of the sole defining an interior of the article of footwear, and the insole positioned in the interior of the article, are also provided.

Disclosed is a waterproof shoe with an improved ventilation mechanism, designed to circulate air from the outside environment through the shoe in order to provide convective cooling to a wearer's foot. In a desired embodiment, the shoe may incorporate a pump-ventilation mechanism which, coupled with airflow channels incorporated in the upper, acts to establish continuous substantially one-way airflow through the shoe in a heel-to-toe direction while a user walks.
