Choose your front and back disks to fit your shoes
Men's shoes require medium for the back disk and large for the front
Women's shoes require small for the back disk and medium for the front disk
(small disk is not available as a ring and would be solid without the hole in the center)
Hollow center of the ring provides weight distribution forcing your weight to the outside of the ring providing greater stability
