I think so, yes

@ragingloli
That’s pretty much exactly what I’m looking for. :D

Next time I’ll use Google first.

There are such things…
There’s the actual inline skate shoe – http://www.locoskates.com/product_info.php?products_id=1025
or
there’s just the detachable quadline wheels – http://www.skates.com/Scorpion-Quadline-Strap-on-roller-skates-p/skrpq.htm

I want something like the wheels with the velcro but not quad’s – I want just some really small blades that i can throw into my bag! If anyone finds anything smal like this please let me know!

@chesca
Isn’t what @ragingloli linked to what you’re looking for?
The brand is called hypno skates. These are detachable in-line skates. I’ve bought a pair by now, the wheel frames fit easily into my backpack.

I don’t think you’ll find in-line skate wheel frames that you can attach to any shoe. This is possible with four-wheel skates because those are nicely stable, but for in-line skates I don’t think it would be safe. They wouldn’t stay put.

this looks pretty good:

Wonder if it exists…

@rwt
Yup, it does exist. I’ve owned a pair for a while. (Still do, strictly speaking, but one of them is broken now.)
On mine, that clamp at the heel went up a lot higher, though, and it was secured just below the rim of the boot. That’s for stability.

This question is almost 2 years old. Way to necro bump a thread.
