Adidas Adizero Adios Pro 4 vs Adidas Adizero Adios Pro Evo 3:
Which to Choose

On paper these two sit remarkably close: near-identical stacks (39/33 mm on the Pro 4, 38/32 mm on the Evo 3), the same measured ~6 mm drop, matched cushioning (5/6) and top-tier responsiveness (6/6), and both neutral, forward-tipping platforms tuned for roughly 3:00–3:20 min/km efforts. The defining split is weight and how each achieves its snap. The Pro 4 comes in around 200 g in a men's US 9 and drives propulsion through full-length carbon-infused EnergyRods layered between two slabs of Lightstrike Pro PEBA. The Evo 3 is a different order of thing at roughly 99 g — less than half the weight — using Adidas's lowest-density Lightstrike Pro Evo foam and a U-shaped ENERGYRIM perimeter stiffener instead of a full plate, wrapped in a paper-thin upper. That radical weight cut buys a lot of speed but costs everything else: the Evo 3's platform is even narrower and twitchier (1/6 stability versus the Pro 4's already-tippy 2/6), it's less durable, and it demands flawless form to feel good. The Pro 4 is also the more versatile of the two by range — it's genuinely happy from the 10K up, where the Evo 3 is really only worth its cost over the half and full marathon. In short: the Pro 4 gives you most of the propulsion with a touch more forgiveness, mileage life, and distance flexibility; the Evo 3 trades away comfort margin, durability, and versatility to save you a hundred grams on race day.
