Solution: Find a ski-boot whisperer.
Insiders tout family-run BootDoctors (bootdoctors.com), in Telluride, Colorado, and Taos, New Mexico, as one of the best. There’s also Cosmo’s Footwerks (cosmosfootwerks.com) in Truckee, California, and Larry Houchen at Larry’s Boot Fitting (larrybootfitting.com) in Boulder, Colorado. These guys will make custom foot beds or tweak a liner till it fits just right. From about $30 for a fitting.
