As an novice road and occasional trail runner with pronation and flat foot problems I've looked for a good stability shoe that doesn't look like it was made for a geriatric patient. After fracturing a metatarsal on an 8 mile run wearing a shoe with too much flex, I bought the Adrenaline GTS 17. Way more responsive than my previous Brooks Addiction shoe from years ago that was just too heavy and ugly. I wear a 10 street shoe but bought the 11 for toe comfort, which I do in all running shoes. Foot and knee pain are a thing of the past with the Adrenaline GTS 17. Love it!
