adidas Ultraboost 21 COLD.RDY — Navy / White / Yellow | Women’s
The adidas Ultraboost 21 COLD.RDY (S23754) is a cold-weather performance running shoe that combines the Ultraboost 21’s renowned running credentials with adidas’s COLD.RDY technology — a designation applied to adidas footwear and apparel engineered for cold-condition performance. The Navy / White / Yellow colourway is a bold, high-contrast palette: deep navy as the primary, punctuated by white and yellow detailing for visibility and visual energy. The lace-up low-top construction and synthetic upper provide a secure, structured fit suited to outdoor running in colder conditions. Available in US Women’s 7 through 11 at $114.95, the Ultraboost 21 COLD.RDY S23754 is a premium running shoe for customers who train outdoors year-round and need cold-weather capability without sacrificing the Ultraboost platform’s performance pedigree.

Design Notes
The Ultraboost 21 is one of adidas’s flagship running platforms, and the COLD.RDY variant extends its use into lower-temperature conditions — making it a practical choice for autumn and winter running without requiring a switch to a separate cold-weather shoe. The Navy / White / Yellow colourway is well-suited to both road and track environments: the navy base is clean and versatile, while the yellow accent adds a functional visibility element relevant for low-light outdoor running. At $114.95 across an 8-size Women’s run (US 7–11), this is a strong premium running option for the customer who prioritises year-round training capability.
