I've got an old pair of Sperry Topsider rain boots (9756677 F4-CH17) that have begun to leak. A shop in NYC (not sure if they are members of SSIA but they get rave reviews in the press) told me they couldn't be fixed and even with repairs would always leak. This was based on my description over the phone, not on looking at them. But they are pretty cracked. I wonder what the experts on this forum think and if anyone can recommend a good repair shop in NYC?
