Something happened to the cork sole of my shoes. I’m not sure if it was damaged by something scraping across, or if the cork was already weak in that area, but it definitely affected the integrity of the shoe. I scraped out the soft cork until I reached solid composite cork at the damaged area.

I mixed up some two part epoxy, then mixed the cork particles with the epoxy and filled in the hole with the mixture, smoothing it with a piece of wax paper.

I let it sit overnight then sanded the area. The result seems to be structurally sound, but time will tell. The patched area is darker, but I could treat the whole corked area with a sealant to help even out the color. I might do that in the future if the patch holds. Since it is on the inside of the heel, I’m not as concerned about it.
