The adidas PulseBoost HD LTD M is an adaptive sneaker engineered for responsiveness and maximized stability. Debuted in September 2019, this version comes in grey knit with non-stretch support zones and a reflective forefoot insert. A Flash Orange pull tab and printed Three-Stripes impart a graphical look. The tongue label's QR code unlocks a running playlist. High-density Boost and a Continental Rubber outsole create an energized, stable sensation underfoot.
