Daily footwear should feel comfortable from the moment you try it on. Check that your toes have enough room to move and that your heel stays secure without rubbing. Walk a few steps before making a decision.
Think about where you will use the footwear. Breathable materials may suit warm days, while flexible soles can make walking and commuting easier. For rainy conditions, consider styles that are easy to clean and dry.
Try both feet because foot size can vary slightly from one side to the other. Wear the type of socks you normally use, and choose comfort over a style that feels tight or unstable.
