Did you know? That as species who walk upright, humans put a lot of pressure on their feet. Overpronation-rolling the foot to one side-can lead to hammer toes, arch pain, arthritis, and achilles tendonitis. Keeping feet confined in sweaty, narrow shoes, especially those with high heels, result in bunions, calluses, corns, ingrown toenails, and fungal infections. Those high heels are why women experience four times as many foot issues as men!
