Be thoughtful about getting and using new shoes. Shop for shoes late in the day, when your feet are at their largest size. Look for deep toe boxes and sufficient width. Break new shoes in slowly. Shoes should protect your feet not injure them.
Correct fit is very important.
Wear cotton socks without seams. Change socks often if you have sweaty feet. Avoid knee highs and tight elastic. Cotton socks absorb moisture, keeping feet dry. Tight spots can block blood flow.
