I bought this running shoe without purchasing or even trying on a saucony before. It read as what I needed; a light, flexable, and cushioned running shoe. My feet are very small, and a size 5 is always too big for me, but I can't find many good shoes in a womans 4. This shoe fits perfectly, so it runs about a size smaller than what it should be, but if you have small feet like me, you're in luck. This shoe does not weigh you down and flexes right along with your foot. I highly recommend this shoe to anyone.
