The blades are not worn in every day usage like a regular prosthetic are, they are used to run or jump, if I understand correctly.

I figured a kid could just as easily walk around in them, so could be primary, instead of a spare pair. If a kid had to choose, I'll bet he'd choose the blades. It looks like he caught on to wearing them pretty quickly.

I don’t think they are well suited to walking around, I could be wrong, though. Too slippery, IMO.
