I already had a pair of these shoes but I needed a back-up since I'm training for a marathon. They are for neutral arc feet, very comfortable, light and offer good support. I have knee problems so my main objective in when I'm shopping for running shoes is good shock absorption and these shoes deliver just that. After running more than 100 miles (and counting) with this pair, I can highly recommend them. Amazon shipped the shoes promptly and without a hitch, as usual.
