A few days ago I was looking to BUY something on Black Friday. It will be perfect outside this winter Very disappointed. I wear them almost daily but I only wear them around the house. Not quite as much room as we would like. It has to be the right one because its the only one the works independent of the pair. Rubbish do not waste your money Just a few moments to download and pare devices! Luckily, I had a second pair, but the same thing happened. I bought 2 of these because I have lots of shoes.
