I used to wear my crocks at the pool, but there is too much plastic on my feet. Kind of the selling point of this device. First Person this isnt. At this point I only use my phone for volume changes which is annoying because the main reason I like the touch controls is because the volume button wont break like my last headphones. I purchase a couple, so I can have a mount on each bike instead of moving the mounts around. Im shoe size 5 standard width. But also because the sound and feel of the UE 500vi is really good. If you have an Apple product and plan to purchase more products, I highly recommend purchasing these 3-in-1 brackets. Battery is awesome. The material is sturdy.
