Remember, leather stretches and then molds to the foot. Choose looser-fitting shoes for young children so that the cleats don't affect the growth of the feet. Try on cleats with soccer socks and shin guards to ensure proper fit. Check out the soles. Regulation rubber studs provide traction and stability.
Replaceable studs are only for older, more serious players.
Buy for the short term. Shop about two months before the start of the soccer season, when stores are well-stocked with the best merchandise. Buy from a sports specialty store with knowledgeable salespeople. Buy cleats specifically made for soccer. Choose cleats for either gender.
