It is just the right amount of iift to walk around in all day and not mind wearing them. Made just like Keen brand sneakers except half the price. It looks to me like to get the RGB strips in they lowered the buttons. Which is fine, I’m just starting off. Only drove 55 mph so will update after highway driving. Move it a little and it would not work. I am only experiencing minor irritation of the nerves in my lower back. The only dislike was that the cord for the cell phone was outdated, particular the Apple I Phone and could not be used on the Apple I Phone latest models. I would recommend especially if you’re looking to rid yourself of wires. There is a bit of wind resistance I noticed while biking, but if I push them in more securely, I can hardly notice.
