I got these shoes in size 9 and they fit perfectly! But as I didnt put them on I can not speak for there fit and functionality, Im sure it was great. This was a birthday gift for my gentleman friend, so anything less than authenticity is unacceptable. Pros:Due to the nature of my nine-day trip, I had to travel light. Then I went to Eccos when they were on sale. I use them for walking 10+ miles a day in leather dress shoes. Volume is loud and the audio is crystal clear. They also leak more sound, but nothing like open-back headphones. Aber ich bin sicher, hier schließt Soundcore auch noch auf. and they were very flat.
