Shin splints are often caused by overactivity of the larger and more powerful calf muscles. This can cause a muscular imbalance, tension and pain. Compression sleeves help to ease this tension in the calf muscles. They can also help to improve circulation in the lower leg. This reduces inflammation and provides support for both the calf and shin muscles. It's a good idea to seek advice from a Chartered Physiotherapist. They can make recommendations based on your individual injury.
