When the bottoms of your feet hurt during exercise, it makes getting through a sweat session that much tougher. Poor footwear selections, tough surfaces and improper form can all contribute to foot pain. If your pain persists even after making changes, consult your doctor as you may need medical intervention.
Poorly Fitting Shoes and Socks
Shoes that offer too little or too much support could cause the sole of your foot to hurt. The wrong shoes could angle your arch uncomfortably, causing pain on the bottom of your foot. Head to a sports merchandising store that will perform a free gait analysis for you so you know what type of support you need.
Shoes that are too big or too wide could mean your foot moves around during exercise -- rubbing and causing discomfort. Wearing cotton socks for athletic activity can also cause moisture to build up and blisters on the bottoms of your feet. Opt for synthetic fabrics or a moisture-wicking natural option such as bamboo or wool.
Just standing on a hard surface, such as concrete or asphalt, can cause your feet discomfort. If you run or jump on these surfaces, the chance for pain is greater -- especially if it's a new surface for you. For example, changing your running surface from a treadmill to a sidewalk could be the reason the soles of your feet hurt.
Even if your shoes fit properly and provide support, they could be all wrong for the activity you're doing. You may not have the adequate support in the forefoot or rear foot to protect your sole. A switch from a highly cushioned shoe to a minimalist shoe, for example, could be too drastic of a change for your feet. Shoes help your feet absorb shock. If they aren't doing their job, the soles or your feet may hurt, and you could experience pain in some of your joints, too.
Shoes are specified for certain sports for a reason. For example, wearing soft-soled shoes in a cycling class can cause pain on the bottom and arch of your foot because your foot bends and rubs while in the pedal. A stiff-soled shoe is usually recommended for such an activity to better transfer power to the pedal and keep your foot stable.
Attention to Foot Health
The way in which you exercise can also cause pain on the bottom of your feet. If you tend to drag your feet as you run, for example, it magnifies the contact your feet make with the ground and could cause pain.
Maintaining flexibility in your feet is an important step in preventing pain on the soles. Roll the sole of your foot softly on a golf ball and practice picking up a hand towel with your toes. Walk barefoot occasionally on surfaces free of sharp debris, such as a sandy beach, to toughen your feet.
