The upper support bar popped out of its housing while I was driving, dropping the bikes several feet and causing my wifes rear tire to hit the ground destroying the tire and inner tube. AWFUL! The steps are not very defined, just so so but because of the looseness, its very light and low quality. Another problem I experienced with the 2nd pair is the fact that the magnetic ear pads keep sliding around and are not tightly attached to the metal housing. Surprisingly not a common product to find in stores or online. I am a true size 10 and ordered a 10 and they fit with just enough room for my long toes! I wasnt crazy about the plastic end covers but they are still there. I hope this one works. Bought the same size as my other 4 pairs and have worn Birkenstock Madrid’s for years. Las chanclas no están mal, y suerte que me fijé en las otras reseñas antes de pedir.
