  • Patent number: 5992861
    Abstract: The adjustable foot equipment (10) is adaptable to ski boots, in-line roller skates, ice skates, water skis and snowboards, and includes a base (32) formed with a depending appendage (30) adapted to be joined with a support member (102). The appendage (30) and the support member (102) are formed with complementary engaging curved surfaces that permit relative pivotal movement between a foot holding portion (20) of the foot equipment and the support member (102). Once a desired offset angular orientation between the support member (102) and the foot holding portion (20) is determined, a securing arrangement locks the support member to the appendage. The securing arrangement can be easily released to permit resetting of a selected offset angular orientation. Some embodiments of the invention permit permanent adjustment of a selected offset angular orientation.
