Abstract

There is disclosed a resilient spring and lever support for an inner sole of a shoe which can be used in combination with a new foot warmer mechanism, or can be used as an orthopedic foot support. The preferred embodiment is a foot warmer mechanism which has a pair of sole plates in rubbing frictional contact with the upper sole plate pivotally secured at the toe of the shoe and the lower sole plate supported by a lever arm located near the heel of the shoe. A resilient spring is provided at the heel of the shoe to bias the pair of plates upwardly, and one or more springs can also be provided at intermediate positions. The pair of plates is moved down and up by the applied weight of the wearer and the countering bias of the spring. As the sole plates are moved, they slide against each other, generating heat by friction, to warm the weater's foot. The mechanism can be constructed in the shoe or can be a separate assembly that can be inserted into a shoe.
