Does the weight in ounces on running shoes make a difference in performance?
Yes! - It seems as if ounces don't make much of a difference, yet when it comes to running shoes, picking the right weight (in ounces) can be crucial. For example, It's not the same to run on a 10+ oz. shoe than on a 9.5 oz.; even if it doesn't seem like it will have much of an effect, after thousands of steps on a single run, it certainly will! This conclusion has been drawn by doing various analyses after trial and error.
