Designed for use with Asham or Hardline shoes featuring the Rotator Disk System RDS.
- 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
