FYI: I wear support thigh high stockings most of the time, but when I tried them barefooted, I felt the ridges more. I connect them to the charger for hours and nothing, they continually say low battery and die. La comodidad, el apoyo del arco, la amortiguaciones en el talón, las correas son excelentes, el único inconveniente que note fue que al caminar mucho y con el sudor del pie se siente que el pie resbala, ya que el material de la planta es muy liso. Great quality sound to replace the originals I would not say the difference is enough to render the earphones ability to cancel noise completely compromised, but they are definitely not the same. So that was nice of them only problem is I haven?t had new controller for a month and it?s already acting up. Now that we have to switch screens frequently, this is a pain. Super comfortable and great for long walks. You can do this will all three air chambers. When you put it together, make sure you match up each rod to its corresponding half otherwise it won?t fit together in the end.
