Saucony ProGrid Triumph 4 Winter Solstice Holographic - The Saucony ProGrid Triumph 4 is an iconic sneaker that celebrates the 'retro-tech' aesthetic of the early 2000s, faithfully reintroducing the design from the original 2007 running catalog. This sneaker perfectly blends heritage technical performance with contemporary lifestyle functionality. The upper features a mesh base enriched with synthetic or chrome leather overlays. The shoe's technological heart lies in the ProGrid cushioning system within the midsole, while stability is enhanced by Arch-lock technology on the medial panel, which securely wraps the foot. Completing the design is a midsole structure composed of four layers of dual-density EVA foam, designed to support the foot's natural movement.
