adidas UltraBoost 2.0 Limited 'Silver Medal' (Unisex) Core Black / Metallic Silver Running Shoes BB4077

The adidas Ultra Boost was first launched in 2015 and is adidas’s flagship running shoe. With its innovative design and revolutionary sole construction, the Ultra Boost redefined people’s original understanding of running shoes. Unlike traditional running shoes, the Ultra Boost features no separate tongue; instead, Primeknit knitting technology seamlessly integrates the tongue and upper into a single unit. The entire upper fits like a second skin, delivering exceptional comfort to the feet during running. The Ultra Boost incorporates adidas’s proprietary Boost cushioning technology, with denser Boost pellets providing superior energy return and impact absorption. The signature Torsion System—a torsional stability mechanism—is fully embedded within the midsole and extends continuously from the forefoot to the heel, enhancing overall stability.
