About this product
The adidas Adizero Boston 13 arrived in 2025 with a blue-and-yellow colour combination. Made for men, this Blue Yellow Core Black version uses mesh for the upper, giving the material a visibly open, patterned texture rather than a smooth, continuous surface. Blue and yellow form a clear cool-and-warm contrast, with each colour bringing out the character of the other. That pairing works against neutral clothing such as grey or black, while picking up either colour elsewhere in an outfit creates a more coordinated approach.
