I got a pair of ballroom shoes, the kind that has fuzzy soles (suede). I've only be dancing for 6 months, 4-8 hrs a week. Now the front of the sole is slick and shiny. I think all the fuzz is gone and its just polished leather, but I'm not sure. At first, I thought that it's just dirty and all the fuzz hairs got packed together, I tried cleaning it, and it doesn't seem to be the case. Bottom of the hill is still fuzzy. I got a dance shoes metal wire brush, but I don't think it will do any good if there is no fuzz left to brush. So... do I replace them? re-suede them with one of those kits you see online (or take to the cobbler). How long do these suppose to last?
