Wear 11. Will buy a third time for sure. Astro makes such good quality products but with these the sound being subpar at best and the build quality as poor as can possibly be, I would recommend you bypass this headset. They fit nicely and are well made. Some of us with arthritis/back issues need a shoe with a particular heel height and the Lexi seems to deliver in that area. I got a S/M. The leather-like upper material is nice, and there was plenty of room at the ankle strap. He said they were fairly comfy but caused him to fall down a flight of stairs due to being slippery and then they broke. There has never, ever been a time when Ive put them on the charging doc that both headphones end up charged at the same time. These outlets have affordable/cheap Dove products.
