So you bought this very nice shoe, but it’s too tight for you and makes you very uncomfortable. Here is a way to stretch the shoe a bit without damaging it.
Did you know what you could stretch them in the freezer?
Fill a zip lock bag of water just under half way. Make sure it is sealed well, and doesn’t have air trapped inside. The air won’t really do anything but make it harder to get the baggy down into the toe.
Put the shoes into the freezer. If you are worried about dirt, you could put them in a plastic bag and then into the freezer.
Typically you can freeze them overnight, take them out in the morning, break out the ice, and then repeat once more and leave them in for the next day and night for a little extra stretch. Do not let the bags melt inside the shoes, that will lead to wet shoes, and might ruin them. Most of the time you can wiggle out the ice bag, or break it out with the end of a knife.
