About the adidas UltraBoost Winter.Rdy "Core Black"
An October 30, 2020 release timed to the season it is named for. Winter.Rdy closes the UltraBoost's usually open knit, adding weather resistance where the standard shoe lets air and water straight through, and dresses the result in Core Black with Cloud White and Grey Six for contrast. Dark colours are the sensible choice on a winter shoe, since salt and road spray mark pale uppers within days.
The cushioning is unchanged. A full-length Boost midsole runs the length of the shoe, and the laced midfoot cage still tightens the arch as the laces pull. The price rose to $190, ten dollars over the base tier that year, which covers the treated upper. Winter.Rdy and Summer.Rdy ran as a pair of seasonal labels across the adidas catalogue, each taking the same silhouette and adjusting only what the upper does with air and water.
