Launching as part of a collaborative three-piece pack, the MM6 Maison Margiela x Salomon ACS Pro Advanced ‘Heather Blue Bonnet’ presents a tonal colorway of the trail running shoe. Varying shades of blue are applied to the upper, secured with Salomon’s Quicklace system and featuring breathable mesh construction with durable synthetic overlays. Dual branding appears on the tongue, sockliner, and a pair of webbing pull tabs at the heel. Lightweight cushioning arrives via a dual-density EVA midsole, equipped with a stride-stabilizing Agile Chassis System and reinforced by a lugged Contagrip outsole.
