They fit okay (8. It can charge both at the same time. Also, works great with the iPhone XS. It still works great. They are super comfortable, very stylish and I love them. Besides the comfort, they are the only slipper that comes in my preferred size. These are slightly narrower than usual which is good for me. These slides are well made, good quality, bright white and black. Not sure why Topeak would make such a fragile strap on the front of the baby seat, everything else about the baby seat was good except for that. Over all though, I?m happy with the purchase.
