A bit tricky to fit but once on it mostly fits fine. With a larger size any excess length could be eliminated by twisting the straps so I recommend buying large ! im really happy with these slippers ! Honestly I dont know why people would pay 250 for those Apple buds when there are so many good choices for a small fraction of the money. It can connect with up to 100 other Bluetooth speakers or devices (opposed to the charge 3 and flip 4, which can only pair with one). so in the garbage they went. Returning and choosing a different seller. The screws provided are inadequate, and difficult to tighten, as they are small phillips head screws with a nylon lock nut. Many people had complained of these being too tight, though theyd ordered a larger size, so Id guessed that a regular size might work well for someone with skinny feet like me, and took a chance on these. It was lovely and lasted for hours unfortunately I cant seem to locate a bottle.
