Roller Skates Have Tractor Treads (Jun, 1936)
Roller Skates Have Tractor Treads
LOOKING like a pair of toy army tanks, roller skates invented by a Japanese school teacher are fitted with endless treads like those used on tractors. This novel feature is said to make it possible for users to skate over rough surfaces that would stop conventional skates.
Those Japanese!
What will they think of next!
Oh wait…

I remember seeing something very much like this around 1978. It was used for skiing on grass.
