The women’s Ultra Boost 4.0 in ‘Ash Pearl’ joined a lineup of lifestyle colorways designed for everyday wear in 2017. The reserved look uses a peach tone across the Primeknit upper, midfoot cage, and TPU heel counter. Underfoot, a classic white Boost midsole and black Stretchweb outsole provide all-day cushion for casual wearers and energy return for serious runners.
