I am an avid runner with a neutral gait. As I have always preferred some cushioning while landing, I have been partial to running shoes with well developed cushioning. My fellow runners will chuckle when I tell them about 'saving' my favorite running shoe since the last 7years. the Adrenaline GTS 15 is a decent pair of running shoes and fit my needs. The fit is perfect and nicely wraps your feet. I have gone on fifteen to twenty 5miles jogs wearing this shoe and three to four 10 miles run. Perhaps I am still breaking into the shoe, but I distinctly felt my soles tiring during long runs (the 10 mile runs). My running surface is a mix of tarmac and soft ground (wood chips, gravel) - therefore it wasn't out of ordinary. Overall, I am happy with the shoe - its a great recommendation for anybody going for short runs.
