The adidas Ultra Boost S&L Black Red Blue is a running shoe that features a Core Black and gray colorway with Cloud White, blue, and red accents.

The midsole of the Ultra Boost S&L Black Red Blue is made from Boost technology, which is made up of thousands of tiny pellets that are fused together to create an energy-efficient cushioning system. The outsole features a Continental Rubber material that provides traction on most surfaces. The outsole is also designed with a Torsion System, which helps to provide stability and support throughout the gait cycle.

We believe that one of the most notable features of the adidas Ultra Boost S&L Black Red Blue is its upper construction. The shoe is made with a PRIMEKNIT upper, which is crafted to provide a seamless, sock-like fit. The PRIMEKNIT material is also lightweight, breathable, and stretchy, allowing for a comfortable and adaptive fit. The shoe was released on June 23rd, 2019, at a price of $180.
