These slip-ons should fit snug at first, and then begin to stretch and mold to your feet over time. Depending on frequency of wear, they will stretch between a few days and a few weeks. Please be patient during the break-in process. If your toes touch the edge of the shoe but do not "curl" or hurt, they should be the correct fit as they will stretch. We recommend wearing them indoors for a few hours to ensure you have the right fit. Wearing socks might also help speed up the break-in period. If you shoes need to be stretched in specific places or just slightly more, please bring them to a local cobbler and they will be able to professionally stretch them.
