Use ice to stretch out shoes that are too snug in the toe area. You can do this by filling two Ziploc bags partway with water and sealing them tightly so that there is no air left inside the bags and the water doesn't slosh out. Plop each bag into the toe of each shoe and stick both shoes into the freezer. Leave the shoes there until the ice freezes, then take them out. Pull the bags out of the shoe, then slip the shoes on. The shoes will conform to your foot shape as they warm back up.
