Fits true to size! This cover protects my earbud case and Im hoping will extend the life of my product. Background noise doesnt get into these so I am a happy camper with the Mic. That being said i enjoy this microphone so much that I will be purchasing another one! Ordererd a uk men size 12 clog and received a uk men size 13. I went back to researching and came across the Samson, which also had great reviews. I never wear heels so these were a good height. Funny so my 1 daughter is 15 and my other daughter is 6 and they both equally enjoy wearing these. I will continue to buy him Nike slides but maybe not this one again I have a high arch so was hoping.
