About this product
The Ultraboost 21 COLD.RDY brings adidas’s signature running shape into a colder-weather update, pairing the model’s streamlined silhouette with a deep Legend Ink, Crystal White, and Acid Yellow palette.

The result is a bold men’s sneaker with a sporty, forward-leaning character suited to walking or daily wear.
