adidas Ultra Boost 21 Vivid Red

The adidas Ultra Boost 21 Vivid Red offers the responsive running technology expected of Ultra Boost 21 models in a bold colorway of Vivid Red and Core Black. Although a streak of Core Black can be found dashed across the midsole and on the tongue’s adidas Trefoil logo tag, Vivid Red is the dominant color. The upper is crafted with Primeblue, a breathable, synthetic material made from plastic debris reclaimed from the ocean. Plastic overlays reach across the textile and secure the laces through 4 pairs of eyelets. Like other Ultra Boost 21 models, the "Vivid Red" variant houses a full-length Boost midsole that provides cushioning and additional energy return. What do our StockX experts love about this running sneaker? The lack of bold branding allows the Vivid Red hue to be the main focal point. The adidas Ultra Boost 21 Vivid Red was released on February 4, 2020, and retailed at $180.
