These are not Gillette Fusion ProGlide, emphasis on the ProGlide, blades. I actually received a 9 and it fits exactly. To be worn when there is no rain as there is a hole in the side, so high days and holidays only in the UK lol Just got them this morning , no more worry about losing one of the earbuds , very good fit and well made I usually wear a size 10 in shoes, but my heel was right at the edge of the 10s with no room to pull my feet back and relax the fit when Im standing, so I got the 11s and they fit great! En gardant la boîte en poche et en mettant de temps en temps les écouteurs dans leur boîte, par exemple le temps de parler à quelqu’un, j’arrive facilement à une autonomie pour toute la journée, même en utilisation intensive (c’est la batterie de mon iPhone quasi neuf qui n’a pas suivi ! Not good for a night of fun. This is the second pair of these I’ve bought, they are so comfortable and give great support as I have high arches . The Annadel Parkers arrived and dont even fit on my foot! Im not saying my knee feels great now (see opening statement of this review), but these flip flops seem to have done the trick to put me back at my status quo.
