Some others are said to last only a year or so before the permanent battery fails and you must buy another entire device (and probably learn how to use it again). Hard to explain. These shoes say they are wide and they are actually narrow. That being said, he finds the soles very comfortable and they are warm. I use these with multiple PC computer setups and cant think of anything negative about them. Prior to purchasing my iPad Pro I?ve used my Bose noise Cancelling HiFi Stereo Headphones for several years? a great sound but they are quite bulky for traveling so I decided to switch to the ear bud type headphone. Missing the weight limit sticker but did have stickers and embedded L and R letters and arrows so you know which direction and whether its front or rear bar. I really enjoy these shoes for my 2-year-old. Plus those have major issues and my left bud quit working within a month. So this is my second of the animal prints, which I dont like, but anyway because my plantar fasciitis does not hurt when I wear them!
