ST-4
ST-4 is a minimalist road-running shoe built around natural foot movement. Compared with its predecessor, it adds rubber coverage and raises the midsole topline for heel positioning. Engineered mesh, printed overlays and an internal skeleton secure a roomy forefoot with a snug midfoot and heel. An OrthoLite footbed adds step-in comfort, while the heel has no built-in counter and packs flat.
