Ultraboost 5X Shoes (use code WINTER)

The Ultraboost 5X stands as the fifth generation of Adidas's flagship running line, a silhouette that fundamentally reshaped sneaker culture when it debuted in 2015. The 5X iteration refines a lineage rooted in responsive cushioning and directional design language—a shoe engineered for both road performance and lifestyle wear. The model inherits the Ultraboost DNA: a sleek, sock-like collar, a streamlined midfoot, and the three-stripe's commitment to blending technical functionality with contemporary aesthetics. For runners and lifestyle adopters alike, the 5X represents a mature expression of the platform, balancing heritage with incremental innovation.

Cushioning and construction remain at the core of what defines this silhouette. The Ultraboost 5X relies on Boost midsole technology—Adidas's proprietary foam derived from thermoplastic polyurethane—paired with a Continental rubber outsole engineered for traction across varied surfaces. The upper utilizes a engineered mesh construction designed for breathability and adaptive support, while the socklike bootie design minimizes internal seams and enhances the foot's connection to the shoe. Weight has been carefully controlled across iterations, keeping the 5X competitive with contemporary distance trainers while maintaining the responsive feel that defined the line's breakthrough moment.

At $100.80 after applying code WINTER at checkout, this represents a substantial markdown from the standard $180 retail price. For a contemporary Boost-equipped runner still in active rotation at Adidas, a 44% discount is noteworthy—particularly for buyers seeking a proven performance platform without premium pricing. The Ultraboost line has demonstrated remarkable durability across seasons and trend cycles, making this deal valuable for those treating the shoe as a core rotation piece rather than a one-season statement. Adidas typically sizes true to length on the Ultraboost line; wider-footed runners may benefit from sizing up a half size. Availability may vary by colorway and size, so securing stock sooner rather than later is advisable.
