I had the guide 7 (owned 3 different pairs) , really liked those then went to the guide 9's didn't like those at all as they took the arch out of the shoe. The Guide 10's are just okay they are not great, made my toe box go numb. Not sure if Saucony changed where they are being manufactured or not, but they are starting to go down hill. I ordered the Omni this go around lets see if I'm changing brands...
