The adidas Ultra 4D 'OG' sneaker draws inspiration from the iconic color scheme that first gained popularity on the UltraBoost model back in 2015. However, this particular iteration takes a bold step forward by replacing the traditional Boost cushioning with adidas' revolutionary 4D midsole technology. This distinct midsole is constructed using a unique lattice structure, composed of a blend of liquid resin, light, and oxygen. Moving to the upper, a sleek black knit material provides a comfortable and stylish foundation, further enhanced by a tonal midfoot cage for added support. To add a touch of contrast, a striking purple heel counter is incorporated and embellished with the Ultra 4D branding, completing the design with a dynamic flair.
