This place has convinced me to take my old shoes for repair and polish instead of tossing them out and getting new shoes! They are fast with their service - same week for adding protective soles on the bottom of boots and next day for polish.
I have this pair of ankle booties with a heel and I was always annoyed with the clicking sound. This place added a quiet sole on the bottom so now it's a lot quieter! I'd definitely say don't get the antislip sticky pad that you can get from stores like Aldo and Nine West and bring it here to get a protective sole done.
Con: sometimes they don't call you to tell you your shoe is done which may result in unnecessary delays.
