Professional Model Powerizer:

The professional model carrys all of the same featurs as the adult model powerisers, with the addition of:

- a new axle to footplate to make it roate with your ankle's movement
(makes it more natural to walk, run, and jump)

- nylon strap instead of plastic

- more durable rubber stopper at base that is easier to replace

- lightweight aluminum alloy footplate instead of plastic footbed
