There are many different factors to consider if you are trying to find the perfect shoes for swollen feet. You will need shoes that can accommodate your feet at all stages of swelling while also providing comfort throughout the day. Shoes that close with hook and loop may be best for swelling feet because you can adjust them to be comfortable as your feet swell up. You should also try to find shoes that have lots of room in the toe area as well as shoes that are very soft and padded on the inside. Breathable shoes are also a good idea, because your feet will be more likely to sweat as fluid builds up inside them.
One of the main reasons it's so hard to wear regular shoes for swollen feet is because you never know what size your feet are going to be. The size shoe you need depends entirely on how much your feet swell up, and you can't always know to what extent they will swell. This is why it's typically a good idea to select shoes that are made of a very stretchy material. You'll also need to look for shoes that close with hook and loop so you can be sure your shoes are secure to your feet no matter how much they swell up.
