This is my first pair of Saucony's and they are the best shoes out there.  I have been an Asics wearer for the last 8 years but recently started getting foot cramps wearing my 2150s.  I have one flat foot and I am a slight pronater and I'm over 250 pounds.  I walk for excercise every day.  After getting these bad boys I went from walking a couple miles a day to 3 or 4 miles and no foot cramping whatsever.

Highlights of this shoe are big toe box, great stability, and the built in sock liner adds extra comfort.  Absolutely no break in period.  Just put this puppies on and you are good to go.
