To ensure proper fit, make sure that the cap of the shin pad is centered upon the knee cap. The flaps of the shin guard should wrap around the calf. Shin guards that are too large have two problems. If it is too long, the pad will extend down into the skate, preventing proper flexing of the ankle. If the knee does not fit into the cup of the shin guard, it will not be properly cushioned during impact, which easily leads to injury.
Measurements for Shin Guards – Select your height from the chart below with the corresponding shin measurement. The measurement is taken from the middle of the knee cap to the ankle bone or the crease of your foot/ankle joint on the front of your ankle. If you wear your shin guards tucked behind the tongues of your skates then you may want to drop down 1 size for the best fit.
