Wow, this is cool! A "starting wedge" for backstrokers. Looks like it's approved by FINA; it's on their YouTube page.
How to use the backstroke foot ledge:
- At the start, the toes of both feet must be in contact with the end wall or face of the touchpad. Bending the toes over the top of the touchpad is prohibited.
- The ledge may be adjustable to 4 cm above or 4 cm below the water level.
