A structure for inserting an insert member of an attachment, etc., into a concave receptacle portion embedded in a shoe sole and removably pinching and fixing the insert member inside the concave receptacle portion with an elastic member, the structure being capable of permitting the removal of the attachment with a wrench for a screw. The structure is constituted as follows. First, the structure has a concave receptacle portion embedded in a shoe sole and an attachment having an attaching/detaching tool fitting portion formed on the shoe sole side and an insert member that is to be inserted into the concave receptacle portion and is formed on the opposite side. Second, the insert member is inserted into the concave receptacle portion, and inside the concave receptacle portion, the insert member of the attachment is removably pinched and fixed with an elastic member. Third, a pushing-up gradient surface is formed on one side of the concave receptacle portion side or the insert member side, and a copying portion for copying the pushing-up gradient surface is formed on the other side. Fourth, the attachment is turned with an attaching/detaching tool to remove the insert member from the concave receptacle portion.

Connector for attaching and detaching attachment to/from shoe sole

A connector includes an insert member for seating within a socket embedded in a shoe sole wherein it is removably fixed with an elastic member, the connector permitting the removal of the attachment with a wrench engaging a tool fitting portion formed on the shoe sole side. A first camming surface is formed on the socket and a second camming surface is formed on the insert member. The insert member is removed from the socket using a wrench to turn the second camming surface relative to the first camming surface.
