This is my 4th pair of the Brooks Cascadia trail shoes. I love them! Even though I normally run on bike lanes and sidewalk paths, and never trails, these shoes fit and feel great. I never feel any shock in my knees when running with these shoes. All my other running shoes, no matter which store "fit me", I always have had a burning issue on the ball of my left foot. Even my foot doctor couldn't fully explain why, but my narrow foot and the long second toe issue, doesn't help the situation. I tried every kind of sock thinking it was the problem, but after I tried these Cascadia 7 trail running shoes, I don't run with anything else and no more burning problem on the ball of my foot!
