5 or 7, depending on the shoe. Upon inspection, after my first set, I notice the clamps had slipped about 1 inch? Huh? Really?? For me, I am only using them for deadlifts I can see the bar while they are in use so its not that dangerous, but for squatting or pressing serious weight ??? I think you need to go to a higher price point to ensure your own safety. Dont expect too much of a set of earphones, and these should hold up for the next 3-6 months. Found them cheaper on Amazon than listed online. Having all three wireless devices (iPhone 11 Pro Max, Apple Watch Series 5 and AirPod Pros) that needed charging each night, I figured I would give this a go. The sole is grippy and solid, and the slippers are soft to touch. Se. My husband never thought that they would still be made let alone that he could buy an almost identical pair on line for such a great price. At first when I looked at the reviews for these head phones, I read all the reviews and it seemed like everyone said they were huge. I have chronic back and leg problems and I can wear these and walk without as much pain, I may even purchase another pair to have when these wear out or get eaten by our puppies, LOL.
