I attended a seminar on Osteoporesis and Arthritis last fall, and a woman
in the audience highly recommended this shoe.  I waited until after
having foot surgery in the spring to order it.  I've been wearing it for
3 weeks and it's wonderful. The sizing is true, fit is perfect, and the
comfort and stability make it worth every penny. I don't train, only use it for walking, but I imagine it would work just as well in any program. This vendor also sells it at the lowest price I've seen online.  Super buy!
