Sizing can differ from product to product. For specific info, check the sizing section on the product in which you are interested.
Your slippers should feel slightly tight at first. The elastic laces and general flexibility of TIME slippers allow the uppers to form to your feet. After about two weeks of use, the uppers will relax and mold to your foot for a perfect fit.
If you are in between sizes choose the bigger size for Summer Slippers and the smaller size for Classic Winter Slippers.
Do not go up or down more than a half-size away from your normal size
