I have very wide flat feet.  These are light in weight, much lighter than my New Balance.  They are nice and wide in the toe box (4E).  This is a good thing because I just bought some Asics 4E that pinch my toes.  The Avia have a very high arch, I can feel the pad in my arch.  This is good for me because I have no natural arch.  It feels like a spring in my step.  I'm very happy with them.  As a bonus, they are inexpensive.  I normally buy New Balance, but these were cheaper so I thought I would try them.  I'm going to buy another pair.  Because of coupons, sadly Amazon doesn't have the best price.  Too bad, Amazon is great.

BTW, I'm a 9 4E in New Balance and the 9 4E in these shoes fit perfectly.

Edit: down to three stars for durability.  I can get almost a year out of these shoes but my kid gets 4-6 months.  I know kids are hard on shoes but still these wear out fast, faster than New Balance or other brands I have bought.  My middle son has had a pair for two months and the sole where it sticks to the front of the shoes is already coming apart from the shoe.  This was ok when these were $20 but not at $38, better getting New Balance.
