UltraBoost rLEA Lab 'Black Sonic Ink'
The adidas UltraBoost rLEA Lab ‘Black Sonic Ink’ delivers a chukka-boot interpretation of the responsive running shoe. The black Primeknit upper features exaggerated cross-stitch detailing throughout the forefoot suede overlay. Affixed to the lateral ankle, a woven Leatherknit tag nods to the collar material, which is made with a blend of shredded leather waste and recycled polyester. Lightweight cushioning is provided by a full-length Boost midsole, reinforced underfoot by a Stretchweb Continental Rubber outsole.
