I have narrow feet with bunions and a high instep.  It's difficult for me to find a good fitting shoe.  I've just received my second pair in 3 years.  The medium width accommodates the bunions, cutting the hidden elastic on the top accommodates my high instep and the shoe still stays on my foot.  These are oh so comfortable!!!  Clarks really hit a home run with this shoe!  No wonder it's so popular.  This shoe is good for normal feet and for problem feet like mine.  I really hope Clarks can make more of this type of comfortable shoe, perhaps in a fancy loafer style?
