These fast changes of movement with the extra grip provided by the boots can place significant forces on both the foot/ankle complex and the knee joints. These forces can be further increased with poor body biomechanics.

Injury is regular occurrence in both of these sports as well as the probability of acquiring an Orthopaedic condition. Some of the common ones are listed below, with more found on our conditions page.
