Heelys

Heelys (formerly known as Heeling Sports Limited) is an American brand of roller shoe (marketed by Heelys, Inc.) that have one or more removable wheels embedded in each sole, similar to inline skates, allowing the wearer to walk, run, or, by shifting their weight to their heels, roll.

Braking can be achieved by lowering the back of the foot so that sole contacts the ground.

[3] The manufacturer says, "We highly recommend [the use of protective gear] when the wheels are in the shoes.

"[4] Most users do not wear protective gear because the shoes are worn for everyday use[1] (unlike more specialized sporting equipment such as inline skates).

[5] The journal of the American Academy of Pediatrics published a study[1] of injuries resulting from the use of Heelys (and Street Gliders, a similar product that is strapped onto regular shoes).
