Really enjoy using this. Im just paranoid like that. Wow, just wow! I could not get the total amount paid back. this makes pads even more important which is why i am so sensitive about seal. LIGHTWEIGHTThese things weigh nothing and that?s what helps support their excellent fit and comfort. i bought for comfort not appearance but they are lovely and pretty on so win win! This gives a bit more space for shoes and is easy to clean under without moving the entire unit. It?s a synthetic upper so it?s a tad stiffer than leather, but they are comfortable. The main issue which I faced was a continuously low volume via the device.
