5M just fine as long as they have a spacious toe box. RE-ORDERED IN A 7 AND THE FIT IS PERFECT The design of my older rack works much better. (Xbox One) it doesnt have the deep bass like the beats do but is good enough. The touch screen buttons for volume, mute, end call etc all work flawlessly with my windows computer using Skype for business (formerly Lync). Easy to install, lock & unlock. Other than that assembly was pretty straight forward. I’ll try it out this weekend for an outdoor kids football game. I had awkward, wide feet and these fit like a dream. We didnt have any problems setting it up and it connected with our speaker right away.
