Adidas UltraBoost 20 Black EG1341

Built for Comfort and Response

At the heart of the UltraBoost 20 is the adidas Boost midsole, constructed from thousands of energy capsules that deliver a springy, responsive feel with every step. Whether you are logging miles on the road or spending a full day on your feet, the cushioning works to keep each stride feeling light and energized. The dual-density construction adds support without adding bulk, making the shoe suitable for both running and all-day casual wear.

Adaptive Fit That Moves With You

The adidas Primeknit+ textile upper wraps the foot in a breathable, ultralight layer that adapts to its shape. Tailored Fibre Placement is engineered into the knit to provide a locked-in fit where you need it most, helping the shoe feel secure through varied movement. Reinforced weaves at the toe add durability in a high-wear area, while the revamped Three-Stripes cage integrates with the lacing system to hold the midfoot in place.

Traction and Stability for Every Run

A Stretchweb outsole with Continental™ Rubber provides flexible grip across different surfaces, bending naturally with the foot through each stride. At the heel, a 3D frame is secured to a neoprene heel counter, adding structure and stability to the rear of the shoe. Together, these elements help the UltraBoost 20 feel grounded and supportive, whether you are running or walking through the city.

A Versatile Black Silhouette

The Core Black colorway gives the UltraBoost 20 a clean, understated look that transitions easily from the gym to casual outings. The monochromatic design pairs with a wide range of athletic and everyday outfits, making it a practical choice for buyers who want one shoe that works across multiple settings. As part of the ISS US National Lab collection, the design draws on NASA-inspired technology testing, adding a distinctive story to the silhouette.
