I just received my Saucony Kinvara 8 Running Shoes (sneakers). I have owned several pair of Saucony in the last ten years. If you are familiar with the other models, these fit similar to to the Fastwitch and Virrata. They are smaller than the Cohesion. I wear a women's 8 medium, but these are definitely - tighter fight than the Cohesion. I can wear them and they are comfortable, so no exchange is necessary. Most people would probably size up 1/2 size. If shows were made in a 7 3/4ths, that would be me! You will find them to be a little more fitted in the ankle and not a lot of wiggle room for your toes. I swear by Saucony. They are comfortable and I wear them every single day of my life!
