Men's Adidas Adizero Adios Pro 4

About this shoe

The Adidas Adizero Adios Pro 4 in Core Black Iron Metallic Carbon is a premier marathon and distance racing shoe featuring a completely redesigned architecture across every component from its predecessor the Adios Pro 3, applying a new generation of Lightstrike Pro foam formulated from TPEE with an updated compound that delivers the brand's softest and most resilient version of the material to date alongside the retained Energy Rods 2.0 system of five carbon-infused rods that mimic the foot's bone structure across the full length of the midsole, delivering torsional rigidity and propulsive energy return in a platform that weighs just 7.1 ounces in men's US size 9 at 39mm heel and 33mm forefoot stack heights with a 6mm drop. The Core Black Iron Metallic Carbon colorway applies the most classic and race-focused visual treatment in the Adios Pro 4 lineup, with the dark base and metallic accents creating a visual identity that connects directly to the performance and racing heritage associations of carbon-plated super shoe aesthetics while contrasting against the lighter and more visibility-forward colorways available elsewhere in the range. The new Lightstrike Pro foam's TPEE update marks a significant departure from the denser Adios Pro 3 formulation, appearing dramatically more airy and plush under microscopic examination at the cut foam level, and delivering a more compressed and cushioned feel that extends energy return throughout marathon distances in a way reviewers noted as maintaining spring well past the 20-mile mark where some racing shoes lose responsiveness, though the softer compound trades the exceptional durability of the previous formulation for greater immediate performance. The new Micro Fit upper is an ultra-lightweight and nearly transparent mesh that eliminates the stiffness and abrasiveness of the Adios Pro 3's upper, fitting slightly narrow compared to the previous version, and the improved eyelet design eliminates the fragile first two eyelet lo
