Available in elementary school sizes, the adidas Ultra Boost Uncaged J presents a simplified version of the performance runner. By eliminating the typical midfoot cage, the shoe emphasizes the combination of grey and black on the Primeknit upper. To enhance both comfort and stability, the laces are strategically arranged in tiers, working in harmony with the adaptive-knit collar. Moreover, the black heel stabilizer matches the rubber outsole, while the full-length Boost midsole brings a striking white contrast.
