The adidas UltraBoost 1.0 rLEA Lab ‘Off White Sonic Ink’ pairs neutral tones with sustainable materials. The patterned Primeknit upper features a blend of recycled polyester with shredded leftover leather spun into the yarn fibers. Tan suede is utilized on the heel counter and forefoot overlay, featuring exposed stitching for an unfinished aesthetic. The lightweight build rests on a full-length Boost midsole, supported underfoot by a Stretchweb Continental Rubber outsole.
