ORIGINAL: Bought this set to replace an older version. 5cm+ in length. I am a 6 in most shoes but wear a 5 in tevas. When the hooks arrived, they have their logo HUGE across the front of the hook. arrived well packed, on time and fit perfectly. Overall audio is clear, surprisingly a lot of bass! ???? Covid makes everything much harder. Highly recommended used daily I was looking for a comfortable "go to" shoe for hanging around in.
