12/10 Mind you, this is a 19" bike frame. You can tell by the photo Ive already been wearing these a lot. I dont understand the design/business justification for shrinking the sole width of recent Rockport shoes. The ear pieces are magnetic which is a nifty feature, but not a requirement for me. The soles are very comfortable though. No old-lady orthopaedic shoes for me! It?s, I guess, water resistant. I found them to be perfect indoor house slippers especially in colder weather. you name it.
