In martial arts shin to shin contact, even when unintended, is common when sparring. A good pair of shin guards is essential to absorb the impact. We have both cloth and dipped foam stile shin guards in assorted sizes and colors.
Whether required or not, shin protection while sparring in any martial arts style is desirable. Cloth shin guards offer a basic level of protection but offer the advantage of a breathable material and light weight. Dipped foam and some other shin guards offer greater protection with an additional layer of padding right over the shin bone where it really counts. Everyone has their preference but check with your instructor to make sure a specific type is not required.
