Maximum performance. With its seamless, flexible and form-fitting knit upper that hugs your foot perfectly, the very lightweight McKINLEY women’s Flysome AQX is the go-to shoe for trail runners, sporty hikers and trekkers alike.

Its innovative midsole construction marries an extremely low weight with a high shock absorption around the forefoot and the heel. Pro Cushion guarantees superior comfort and was designed for long-lasting functionality. The outsole’s aggressive profile takes on every terrain with ease.
