The adidas UltraBoost 20 Lab ‘White Signal Green’ showcases neon accents on an otherwise neutral colorway of the performance running shoe. The sock-like upper is constructed from white knit textile with contrasting black three-stripes in a reflective finish. Bright green pops of color land on the translucent heel frame and a rearfoot lace lock connected to the lacing system, which incorporates a series of lace loops in a matching green hue. Responsive cushioning arrives via a full-length Boost midsole, reinforced underfoot by a black Continental rubber outsole.
