• Lightweight engineered jacquard uppers provide structure, breathability and midfoot lockdown thanks to their durable fabric • Tongues feature strategic cutouts for breathability • Early stage Meta-Rockers help ensure a smooth ride • PROFLY™ midsoles offer cushioned landings and propulsive toe-offs • Rubberized foam outsoles provide lightweight ground contact and responsive cushioning Great shoes, super comfortable. I love Hoka in general, selling because these weren't the best for me. I wore them 1 time on a treadmill and haven't worn them since. Great neutral running shoe with max cushion!
