ABSTRACT:
A non-slip support shoe for attachment to the end of any crutch or other walking aid comprises an attachment cylinder for attaching the shoe to the bottom of the crutch or walking aid; a pair of strip leaf springs, at least one of which is connected to the attachment cylinder; and a rubber sole provided on the bottom surface of a lower one of the strip leaf springs. In operation, when the maximum weight of a body is exerted on the crutch or walking aid, the strip leaf springs change configuration (i.e., flatten) so that the entire sole located on the lower strip leaf spring contacts the ground, thereby preventing slippage during use of the crutch or walking aid. Once the maximum weight of the body is removed, the strip leaf springs return to their original configuration so as not to interfere with the angled forward and backward positions of the crutch during use.
