Story & provenance
The Foam IS The Outsole
Under Armour launched the Curry Flow 9 on November 19, 2021 at a 160 dollar retail price. The headline tech was UA Flow, a midsole foam compound that replaced traditional rubber on the outsole entirely, with the foam itself acting as the contact surface. WearTesters, HoopsGeek, KICKZ, and Under Armour's official channels documented the construction in detail, with the Curry Flow 9 building on the Curry Flow 8's introduction of the tech. The UA Warp upper used a cable lacing system reviewers described as feeling like seatbelts across the foot, and the modified Flow traction pattern delivered surprisingly strong court grip without rubber. Stephen Curry wore the shoe through the Warriors' 2022 championship run, and the Flow construction became a defining identifier of his line going forward.
