I polished off the grooves of the thinned shoe sole with a disc grinder and pasted after degreasing, but the adhesion of the adhesive tape was weak and it got peeled off before using it. There are various strengths on adhesive tape, but is this using the strongest adhesive tape? Although it will not be usable as it is, if you can prepare something adhesive, can the shoe sole itself be used for salvation?
It is in accordance with the curve of the shoe sole, but small in size, can not cover up the seam of the shoe sole.
In a little more big size, I thought that if there is a thing that can be cut to fit the shoes.
The included sandpaper, it was hardly to a little work a small size. (From two small, it is better the one in)
