This is a 5 star product. I was asked to try these in exchange for a review. Lightweight fits well around ears. Its a little ridiculous, the shelves are too small to fit a pair of men size 8 shoes. It makes vocals and instrument-based music come alive. They are the correct size for me; they just need considerable breaking in. So thats pretty loud for a mouse, louder than a flesh and bone mouse for sure! I steamed it, and it still wont lay flat (see pics). My Birkenstock size is 41 in some styles, 40 in others, while in European shoes (like my biking shoes or others made in Europe, Im generally buying 42 or sometimes 43). And right after that I notice the skates are already worn out.
