Aloha,
The shoes are fantastic, this shoe was suggested to me by my PT, he suggested this particular shoe because it offers the best arch support in this style.  I agree, and the quility of this shoe is unbeatable, another big plus is the fit of the shoe is right on.  Amazon, offers a great service here and they have been able to save me between 40-60$ every time I buy these same shoes from this site and I replace these shoes every 3-4 months.  Amazon saves me time because i do not have to go in to the store, plus the nice shoe sales people don't know anything about the support this particular shoe offers.
mahalo
