My son swears by the fit and durability of these running shoes.  The price is great, since the first pair I purchased through Amazon a couple of years ago cost $129.  When I saw the price of these, $71, I decided Id better buy one for backup.  He runs daily in these shoes and through difficult terrain.  He runs one day a week 15 miles on a route that sometimes takes him 2,000 vertical feet.  The shoes have held up amazingly, no arch breakdown or run over on the sides.  These come highly recommended.
