Anyways I?ll check in a bit later for longevity but dang I love these things. I have wide feet, but also a tall arch- double cursed. I bought two of these and I should have returned them but the time got away from me. Last thing you want is to have the bike fall from the wall and injure you or others around you. Great support. An orange discolouration has appeared in five different places now on both pairs. Great for the price, great sound, good fit, holds a good charge. Plus I can fit just about all mine and my boyfriends shoes. Will buy again ?? If it were not for missing instructions I would have given it 5 stars.
