UltraBoost Uncaged J 'Black Grey'
Offered in grade school sizes, this adidas Ultra Boost Uncaged J delivers a minimalist take on the performance runner. The shoe lacks the usual midfoot cage, allowing the mix of grey and black on the Primeknit upper to stand out. The tiered arrangement of the matching laces act in tandem with the adaptive-knit collar to enhance comfort and stability. The black finish on the heel stabilizer is repeated on the rubber outsole, while the full-length Boost midsole offers a contrasting pop of white.
