A coating of vulcanizing cement is appliedover they entire rear surface of the holder and disc and then placed in theshoe with the tabs bent to tuck beneath the sock-lining and lap upon the top surface of the inner sole. The pad is readilyand easily fitted intothe shoe-and 'a pair of pads are usually merchandised with a small tube of cement although it is possible to merchandise the productwith its rear side coated with a remoistening adhesive. The use 01' a vulcanizing cement, however, produces a more durable adhesion which is not apt, to loosen from the heat and moisture of the foot, I

In making the disc from a sponge rubber stock in which the pores are very small, a very soft velvet-like friction surface isobtained which will hold the shoe to the foot against slipping, preventing any rubbing action upon the foot or stocking, avoiding injury to the foot and wear to the stocking and the yielding characteristics of the pad or disc offer considerable comfort to the foot. y

Having described my invention, I claim:
