The adidas Ultra 4D Core Black Solar Red is a piece of technological footwear built through extensive research done by a tech firm called Carbon, some top athletes, and the adidas brand. Its upper is black and made using adidas's proprietary FORGEDMESH technique. In contrast, the outlining of the Three Stripes lace cages, adidas tongue branding, ULTRA 4D insole wording, heel counter and inner lining are painted in a brilliant Solar Red. Other than the bright color accent, the sneakers also feature a touch of dark gray hue on the forefront, all-embracing the padded ankle collars. The word "Ultra 4D" is also imprinted in big letters on the heel guard at the back. A full-length digitally printed 4D sole serves as the foundation below, offering the utmost comfort and absorbency with each step. What our experts find as the most intriguing features on the sneaker are the uniquely crafted lace cages and the 4D printed underfoot, which give the shoe maximum support and efficient cushioning respectively. In addition, the brand's mesh technique allows for breathability. The adidas Ultra 4D Core Black Solar Red debuted on December 16th, 2020, and sold for a price of $200.
