This is important because my younger son always removes his shoes upon entering a vehicle. One thing of note is that the directions read more like a part list. We decided to keep them and if that bare metal area starts to get rusty or look bad we?ll pull them off the car and paint them with some black rustoleum or something to prevent rust. Per ora queste cuffie fanno ben sperare. This pair also runs small. My husband easily assembled it and it looks better than the pictures. Just put in your ears and get a solid fit. SOUNDThese sound much better than I imagined. A bit too ridged but they are great for snow. I get an idea that he needs a new pair when I slip into them to grab the mail.
