A replaceable shoe sole for athletic shoes, work shoes, casual shoes, and the like, utilizes a ridge/groove interconnection to permit the replacement of the sole in the event of wear or damage. The ridge, which is undercut, mates with the groove of a corresponding cross-sectional configuration to provide the retention force necessary to maintain the replaceable shoe sole in position adjacent the mid-sole of the shoe. Certain improvements comprise the use of projections and matching cavities adjacent the ridge/groove interconnection to provide additional retention force against lateral and twisting stresses which are placed upon the replaceable shoe sole during use. In addition, the groove is provided with a starting area in order to facilitate the attachment and replacement of the sole. Also disclosed is a replaceable toe which is attached by means of a similar ridge/groove interconnection, and a clamping device for providing additional retentivity. |
