Perfect shoes for me. I would never have discovered this without the staff at Jackrabbit

This shoe is a fantastic shoe if you are a mid-striker who is also a pronator. I am a 3 time NYC marathoner, and have been running for a long time. I will break down the key rating elements in order of importance to my fellow long distance runners.
1. Fit. A+ rating. This is where the shoe shines. This shoe fits like a glove and the fit is dialed in. I prefer a shoe that hugs the foot and is not roomy but more on the hugging / slightly snug fit. This is the shoe for that. It does not have a wide toe box, but a normal one and the toe height is on the lower end. Hence a nice glove like fit.
2. Cushioning. A rating but with a big caveat. I am new to the Saucony franchise (having run in Asics Kayanos for the past 15 years. About a few years ago, I changed my running style from a heel striker to a mid-foot striker. So cushioning in the mid-foot is now of paramount importance to me. This is where the shoe shines. I prefer a cushioned mid-foot but with cushioning that I can still feel the ground. The Guide 13 delivers on this. It is more of a firmer cushioning with nice shock aborption with a touch of bounce. The shoe performs on more relaxing runs and fast tempo runs. If you are a heel striker, stay away from this shoe. Saucony changed the stability technology on the Guide 13. All previous models had the traditional firmer foam on the medial side. The Guide 13 has a Medial TPU guidance frame now and it feels like striking on bricks if you heel strike. I do not heel strike so I do not notice the TPU guidance frame, but you willl if you heel strike. For runners who need stability (pronate) and heel strike, then I recommend the Asics Kayano or Asics GT 2000 8 (if you like a lighter shoe) - the Gel technology is the best in the business for stability heel strikers.
3. Breathability - B. I have been running only in the winter in this shoe. But the upper is a thicker engineered mesh that I think will not breath as well as many of the Asics I have run in. I still think it will breath just not as good as the upper of Asics, who have always done a good job with breathability.
4. Sizing - I normally take a size 9, but I had to size 1/2 up to a 9.5. Fit is great.

So why did I switch to the Guide 13 over Asics. The midfoot cushioning is simply better than the asics. The asics mid-foot cushioning is good but it feels flat with little energy return. The Saucony has that little pop of energy return in the midfoot when you mid-foot strike. So the Saucony Guide 13 is a better shoe for a faster tempo run, which I often do.

Hope this helps, happy running.

Totally satisfied with my purchase, Saucony makes great quality shoes with arch support. I was using Saucony previously and back to Saucony Guide this year again.
