No wires, hence no tripping hazard. They look like hiking shoes! We tried numerous batteries and still nothing. I was very disappointed with these. I bought it to be a macrame station for my bedroom and I?m incredibly happy with the end result. I even replaced the elastic bands with more secure zip ties. The wool wicks away wetness and they stay dry even with heavy use. At first my 8yo said they felt bumpy and weird, but within a couple minutes he really liked them - like his feet were getting a massage. Required allen wrenches are included with the parts. I highly recommend this controller to people looking for one controller suitable for multiple platforms.
