    There was this little kid at the takeaway last night with lights on his shoes. When he walked, the three lights lit up in turn. I'd seen other kids with lights on their shoes. Can somebody briefly explain how those things work? Are there batteries in there?

    Pressure switch connected to flashing LEDs. Usually use button batteries.

    Thanks. Where is the switch, and where does the battery go?

    I'm pretty sure that the batteries are built in to the sole of the shoes, and they are not replaceable. Basically, when the batteries die, throw the shoes away and buy new ones.

    Just like many kids toys that talk or play music.

    Or, just wear them as, you know, shoes..... :D

    So there's no battery compartment or anything that would be uncomfortable, it's all just in the rubber sole? Interesting, thanks. They were pretty neat shoes. :lol:

    My son had a pair. They worked off a spring loaded switch mechanism. I.e vibrations make the circuit complete and the Leds light up. Batteries were built in and non replaceable.

    The batteries probably last ages, I bet. How much power does a tiny little light use, and they aren't running constantly. With little kids they grow so fast, they'll probably grow out of a pair before the battery runs down anyway.

    Same concept as those light-up balls you often see in the Charlie Cheapy shops - sealed unit, some sort of cheap motion/vibration/impact sensor, low power LEDs, throw away when the batteries go flat.

    Or dissect it as an organ donor to Frankenstein the innards to something else the kids can play with - grafted a few over the years into upgrading various toddler toys for the Squirts to muck around with...

    Some shoes have a little USB charger port on them as well.

    Only thing that concerns me about the plug in type is the battery. Do you really want your little one running about, and jumping on top of a lithium cell? ;)

    Why? Might it explode or something?

    I've seen some gutted on you-tube - they have a small lipo inside and a charge controller. If the cell isn't protected properly from the normal abuse kids shoes get when running and playing, then yes, there is a possibility it could explode or catch fire. Not good when its in close proximity to a child's foot.

    But if it's encased in rubber, isn't that sufficient protection?

    I would not be worried, there are a lot of these about and such a thing would be all over the news had it happened.

    The tiny cells are very unlikely to produce enough heat to cause problems, mostly they just get hot and swell up even if you charge them to 6+ volts

    Eh. Lots of current difference between a lithium coin cell and a lipo pack. One can catch fire under dead short the other just goes flat quickly.

    oh, well, thanks. I still think those shoes are cool. I've seen lots of different ones around and about, they draw the attention. They've also got ones with wheels in them, where the kids can skate around. I just wish they'd had those when I was a little kid, I would have loved them. :D
