KIO Approved Karate shin guards are a protective gear designed to protect the shin and foot during karate training and competition. They typically consist of a padded, hard shell that covers the front of the shin and ankle, and a strap or elastic closure system that secures the guard in place. The outer shell is usually made from durable materials such as rexine and is designed to absorb and disperse the impact of kicks and strikes. The inner padding is typically made from foam, and provides additional shock absorption and comfort.
