This thing certainly packs a punch as far as sound goes! The Cutback (51286) is about $10 more and features a memory-foam insole. I wear them every minute around the house. The way they sit in my ear touches the edge of the control which automatically turns the volume all the way up period which is not that loud but very aggravating. Looks good in the photo but is smaller than I expected and was rather disappointed with it. I bought the Sounity orthopedic slides and the first time, I wore them, I knew they would be my go-to sandal. The inner lining material is plastic. Brooks is the man to read on this subject. They are not even close to identical so YMMV in terms of paint job. But please order your regular street size shoe nothing more nothing less!
