In September 2017, adidas unveiled the Ultra Boost Laceless 'Core Black', a seamlessly-designed model that combines style and performance. This iteration of the popular Ultra Boost silhouette showcases a sleek, monochromatic aesthetic across its upper. The wraparound Primeknit construction features a sock-like collar, providing a snug and secure fit, while the midfoot area is adorned with Forged Primeknit for enhanced support. Designed to ensure stability, the heel cup keeps the foot securely in place. Additionally, the shoe utilizes a full-length Boost midsole in a contrasting white colorway, offering exceptional energy-return cushioning for a responsive and comfortable ride.
