I have no idea how this happened, but I look down at my shoe and there is a wad of gum stuck to the side of it. I mean, literally, on the side. It was like a gum wart. Most of it pulled off,but there's still some residual "strands" that held on. On anything else I'd probably use my fingernail to scrape it off but I'm loathe to do that on fine calf. I briefly tried trying to just rub it off with a paper towel but all that did was spread it around a bit. Does anyone have any suggestions? Please?
