I tried vacuuming out the inside with my pet vac (bc maybe it would get all the loose fibers), but it still sheds. I sized up half a size (Im a 9 or 9 1/2) and since I have wider feet and ankles they fit good. It records all audio, including party chat and game volume. When there are no external sounds. If you have such a bag, these little cases might be a consideration. For the curious, Im using these for deadlift volume sets that are currently around 400 pounds. This is my first time purchasing shoes from Top Moda so I will definitely purchase other shoes from them as well. This is great for the price and hasnt given us any problems. Como muchos estoy de home office, lo cual representa que tengo una laptop laboral y mi pc personal. , but I actually like that theyre a bit slower.
