I have great big long flat feet that hurt me all the time - size 10W. I've been wearing the New Balance 410 for the last year, and found them to be quite comfortable. Apparently they don't make them anymore, and this was the closest thing to it. Close, but no cigar. These new 512s are comfortable for the first half of the day, but after a few hours, you start to have heel pain. Or, at least I do.
