Introduced in 2017, the UltraBoost 'Icey Blue' made its sensational debut in the women's collection. This version of the legendary running shoe flaunts a seamless fusion of shades of blue, as the Primeknit upper, cage, and heel counter come together in perfect harmony. To conclude the striking design, a classic white Boost midsole and a durable black Continental rubber outsole grace the sole of the shoe.
