My feet are saying: "muchas gracias!" This is the third pair of New Balance stability running shoes I have purchased. When I slipped these shoes on, I could tell right away that I had waited too long for a new pair. My only hope is that these shoes will provide me with the comfort and stability that my last shoe gave me. It actually seems that each shoe I have purchased has improved along with me. I use these shoes strictly for running. I average about 42 miles a week. I am blessed to be able to run outside year round. A Doctor of sports medicine told me to replace my shoes every 600 miles, an average estament.
