Set new personal bests in the adidas Adizero Adios Pro 4, a cutting-edge super shoe designed for pure speed. At the heart of the Adios Pro 4 lies a dual-layer Lightstrike Pro foam midsole—adidas' lightest and most responsive cushioning to date. Sandwiched between these foam layers is the ENERGYRODS system, featuring carbon rods that mirror your foot's metatarsal bones. The result is a seriously fast and snappy race-day shoe. “I love the propulsive underfoot feel of the Pro 4,” says Kate in our adidas Adizero Adio Pro 4 review. Details: Upper: The new LIGHTLOCK upper provides a secure, race-ready fit with one-way stretch and internal support bands to keep you comfortable and confident while running at top speed. Midsole: Built with dual layers of adidas' revolutionary Lightstrike Pro foam and innovative ENERGYRODS technology—carbon rods that mirror your foot's metatarsals—this shoe delivers exceptional energy return and propulsion. The reimagined rocker geometry triggers forward momentum for an improved running economy. Outsole: adidas' new LIGHTTRAXION outsole material significantly reduces the shoe's overall weight compared to its predecessor. Strategic placement of Continental rubber beneath the big toe adds durability where you need it most while maintaining the shoe's lightweight racing profile.
