5/5

Overall

Since getting back into running I had been wearing Mizuno's and purchased a pair of Paradox while on deployment. They did not work well with my feet at all and I suffered through several months of foot pains and circulation issues during runs. After a fitting and discussion with the staff at the local RoadRunnerSports I picked up these Brooks Glycerin and absolutely love them. While a bit heavier than I would have preferred, they wear great and the ride is amazing. I seemed to be able to feel shoes with 2-piece foam cushioning when I was trying on shoes, but once I put on these I was sold. It has been 300+ miles now and they still feel amazing.

Good, ideal for long runs 8 miles or more. Good for downhills, not much traction for trail but good support in the heel.
