Abstract
Abstract A boot jack to assist in the removal of tight-fitting boots which includes opposed gripping members which are connected at one end by a hinge and which have their remaining ends contoured to engage the heel of the boot. The two gripping members can be spread apart as the heel of the boot is inserted between the contoured ends, and a spring-loaded control member is provided which is engaged by the heel and which locks the opposed gripping members in a spaced-apart condition conforming to the size of the particular boot involved. A second control means is also provided for fine adjustment.
