With over 30-years of running and racing background I average nearly 3,500 miles per year. Over the years I have run in many shoes and tend to go through about 1-pair per month. I am impressed with the One Series shoes in many areas but to be specific the shoe weight, breathability and most of all the cushion and its functionality to perform well in the heel to toe transition with being flexible are its strengths. This is my go to shoe for my daily runs for road and trail. I have run with these as short as 6-miles and up to 24-miles in them and they are a great all around performance choice.
