adidas Adizero Adios Pro 4 vs Adizero Boston 13

The adidas Adizero Adios Pro 4 and adidas Adizero Boston 13 are both performance-leaning models that use carbon rods, but they're built for different roles within a rotation. The Adios Pro 4 is a true super shoe made for racing, especially the marathon, with a highly cushioned, bouncy midsole that feels protective over long distances while remaining very light on foot. The Boston 13 is more of a super trainer, designed to handle interval sessions and high-mileage workouts with greater durability than a pure race-day shoe. It feels firmer and very snappy, with a more distinct response that tends to reward powerful runners, particularly forefoot strikers who can really load and activate the platform.
