Lack of blood may make your feet cold, blue or puffy. Your first step toward foot fitness is wearing shoes and socks that protect, cushion, and comfort your feet. Don't buy shoes at self-service stores. Have shoes fit by a trained fitter. Buy and wear only comfortable, supportive shoes with a low heel and plenty of wiggle room for your toes.
Warm socks are the best remedy for chilly feet.
Don't use a heating pad or hot water bottle to warm your feet because you might burn them. Taking care of your feet every day pays off with fewer foot problems. Wash your feet each day. Dry them carefully, especially between your toes. Check your feet for sores, calluses, red spots, swelling, and blisters each day.
