I love all Saucony running shoes. Have probably both more than a dozen pairs. But I am not a running expert. I loved the colors on these, and they feel like a glove on my feet. However, they are super lightweight and have very little stability base on the bottom. I realized that as an older woman, I need more of the stability cushioning for daily runs. These are awesome for speed work or a race, but less good for training, at least for me. I both a Glide pair for regular workout runs and just enjoy these occasionally. I always size up a 1/2 with Saucony.
