Review on Black Self-Adhesive Shoe Repair Kit - Quick Fix For Heel, Toe, And Sole Holes | Shoe Glue And Blister Patches Included | Heel Toe Protectors For Shoe Damage by Lisa Collins

I'm not sure how the larger size of the sets could be used without cutting them to fit better. I installed the smaller and found that after two weeks that the edges, even though curved to avoid catching, were no long adhering on the last 1/8th inch of the perimeter along the top edge of the hiking shoe, even though below that edge. I'd have expected better. Also, the adhesive layer is whitish and NOT the color of the outer layer, so you will see that edge-on. So, these will work to cover the incipient whole in the inner material of the heel of shoe for some time, but I'm not expecting these to hold adhesively for more than 6 months.
