If like my wife and I, you have more clothes on your rail than expected, the weight of the rail will cause this small edge to crack. I ordered an XL /2X-Lg for size (8-10) and the fit is perfect. I wanted to love these headphones, decent fit, "just enough" battery life (for the gym), somewhat comfortable and decent sound (I also use a set of BeatsX and Bose Soundsport original). I like home automation things, but some of them just too expensive. So if youre on a slight downwards slope and if you plan to shoot horizontally opposite or upwards, this Tripod isnt the right one for you. They came stating 11-12. Although this is not my most favorite style, it is almost as comfortable on my foot as the sandals. I do like them that much. But it?s easy. Highly Recommend it!
