The New Balance P400 “Grey Days” brings the brand’s annual grey celebration into its growing basketball catalog. Covered in a monochrome Slate Grey finish, the sneaker leans on texture, material changes, and layered paneling instead of loud color blocking.
Soft leather and synthetic materials shape the front of the upper, giving the shoe a smooth, structured look. Suede appears around the ankle and heel, adding a richer feel while staying within the same Slate Grey shade. Meanwhile, the light putty grey laces and midsole stabilizing pattern create subtle contrast without taking away from the tonal design.
New Balance continues to expand Grey Days across more than just lifestyle sneakers. This year’s rollout also touches skate, running, tennis, and basketball, showing how important grey remains to the brand’s identity. The theme connects back to the classic New Balance “dad shoe” look that helped make the brand recognizable across generations.
The New Balance P400 “Grey Days” releases April 30, 2026 through New Balance and select retailers in-store and online.
With its muted palette and mixed-material build, this pair gives hoopers and sneaker fans a clean option tied to one of New Balance’s most familiar stories.
