The uppers are very breathable and slightly stretchy, but not too constricting. I got tired of having to use the rental headsets that constantly had microphone problems. Otherwise its a nice dress! These are a good idea in principle, but they just dont work the way I expected them to - ie faster than soldering, and secure. I love these teva?s. I have used this in my backyard to catch glimpse into of raccoons runs around. Cheapest headphones I could find for my kids who are attending online public school since they are always breaking or loosing cheep or expensive pairs of head phones. I can totally see myself buying more pairs in the future. The upper portion of the boot has an elastic band running through it. Light weight, airy, perfect basic style.
