The PUMA Calibrate Runner Mono ‘Black’ combines a snug, sock-like fit with finely tuned cushioning developed in a lab. The sneaker’s breathable black mesh upper is equipped with a knit collar and sheer woven side overlays, providing added support and contrasting flashes of color. The lightweight build sits atop PUMA’s XETIC midsole, featuring a unique foam structure designed to compress with each step for enhanced comfort and rebound.
