I've been wearing this running shoe style for years.  It's a classic.  In terms of sizing, I have a wide foot and usually wear a wide shoe, but in this style I can wear the regular width.  I wear a 1/2 size up in this shoe from my regular shoe size.  I also have high arches. This shoe works well for them and even better when I replace the regular laces (which are great) with elastic laces.
