I have purchased more than 7 New Balance WW811 walking shoes in the last 8 years. Living in MI I wear a black pair for fall and winter and in the spring and summer I wear a white pair of the New Balance.  The shoe is very comfortable for my high arch.  I wear 9M in every shoe purchased and the New Balance 9M shoe is true to size.
Amazon prices are fair, description of the item is very good, and delivery is fast.
