Whether you are a professional athlete or play sports just for fun, the demands made on your feet and lower limbs can lead to a range of injuries, including blisters, sprained ankles, torn ligaments, shin splints (leg pain), knee pain, low back pain and other joint or muscle problems. Added to these are common complaints such as corns, calluses and Athlete’s foot. Your running style, poor footwear and even minor limb length differences can also contribute to sports injury.
