2. Undersized Shoes
Wearing tight shoes also causes swollen ankles. Just like wearing tight pants, undersized shoes restrict proper blood circulation. This causes the fluids to build up around the affected surroundings, which in this case are feet and ankles.
What would be the best thing to do in this case is to avoid wearing those shoes, even if they are your favorite or the only pair in the closet. Sometimes people force themselves into smaller shoe sizes only because they love the shoe so much or they prefer it over other pairs.
If your ankles start swelling, it would be best to stick to the correct shoe size. When buying shoes, always consider the shape of your feet and the type of shoe you are buying. For sneakers, choose the ones that are wider in the toe area and for heels, always choose a size or two bigger than your actual size.
