Updated review: When the seller saw my initial review they contacted me and asked to replace my sneakers at no extra cost and I could keep the first pair. Of course I said yes. After some time the new pair arrived! Unfortunately they were white and not chrome. I contacted the seller again and they offered me a partial refund instead of a third pair or having me ship back the wrong color etc, which I accepted. Once I wore the new ones (which do look great on or off), I was disappointed to discover that the same problem occurred as the first pair - some lights stopped working despite not using them for anything under the "not recommended" section of the instructions, on the first day of wearing them. Additionally, the blue on one of my first pair stopped working entirely.
They're very stylist sneakers on their own, and the company did their best to make sure I had a good experience. I think they're just a fairly delicate shoe and it's a case of getting what you pay for.

Original review: These sneakers look great lit up or not. I put some sport insoles in them knowing I'd be wearing them for lots of walking and they're very comfy. The instructions in the box warn against wearing them for things like running or jumping - things with high impact - which I knew I wouldn't be doing. Unfortunately, even before I got to use the lights at night, the front half of the left one stopped working; I can only guess from too much walking? By the third day I wore them the front half of the right one went out. Both back halves still work and function as they are intended, but it's disappointing that the wiring is so delicate. It seems that the wires just come loose or short out, because the dark parts would occasionally flicker on depending on how I moved my foot, and sometimes the color would be different from the lighted part that still functioned normally. I'm tempted to tear them apart and see if I can fix them myself.

tl;dr - they look awesome unlit and for the price I knew they wouldn't last but I wish I had gotten to use them as intended for at least one night.
