UltraBoost ST 'Core Black'

Designed for distance, the Ultra Boost ST is built with a flexible Primeknit upper atop an energy-returning Boost midsole and Stretchweb rubber outsole. A Torsion System between the heel and forefoot provides endurance runners with stability, responsiveness, and traction. A performance shoe at heart, its mixed colors of navy, black, and burgundy give the sneaker a versatile look that’s also suitable for casual wear.
