They come equipped with a tonal lace up fastening and Flywire technology for a secure feel, featuring a hybrid tongue and soft padding along the collar for comfort. Underfoot, they're sat on an ultra-light React foam midsole, which has a unique rocker design that's shaped for support during all 3 phases of your stride. These trainers are flexible, offer a smooth stride and are wider in the base to keep you stable. With a grippy rubber tread, these trainers are finished up with the iconic Swoosh logo to the sidewalls.
