I took boots here at 10am to have a zipper replaced and they were ready the next day at 8am.
They were shiny and looked good as new. They even took the pull from the old broken zipper and put it onto the new zipper, so the boots match perfectly and you can't tell the zipper as replaced at all.
It was 45 dollars which seems expensive but with the insanely fast service I cannot complain. Other places I called said it would be three days!
If I have problems with any other shoes, I will go here again for sure. I will suggest it to people as well.
