ABSTRACT:
A shoe tree which is applied externally to an article of footwear has a base with a toe grip provided on the front portion of the base, and a heel grip provided on the rearward portion of the base. The heel grip is received and is vertically movable on a post which extends generally vertically from the rearward base portion. A preferred embodiment utilizes a post having a roughened exterior and a heel grip having a throughbore which is slightly larger than the diameter of the post, which is received within the heel grip throughbore. When the heel grip is positioned on the heel of the footwear, the heel grip is tipped rearwardly under the natural bias of the flexed sole to thereby frictionally engage the throughbore wall with the roughened post exterior to fix the heel grip in place on the post and maintain the footwear sole in a straightened condition.
