Looks like a spin on snow blades, except they're designed to use an inline skate, or ski boot. Looks like they could be machined from a piece of plastic or aluminum but probably plastic... hard to tell. Expensive.
yeah they are designed to attach to a rollerblade boot so you can rollerblade in the summer and "ski" in the winter. Some of the "pro" models are about $400 for essentially a very small machined piece of steel/plastic/aluminium. The video is pretty funny. I would have liked to see some people hucking cliffs or some jumps on them!
some places like in the midwest of the us basically only have green circles so I could see how this would be kinda fun in a place like that or korea.
it still sucks
