Our Verdict

Saucony Endorphin Pro 4

adidas Adizero Evo SL

The Saucony Endorphin Pro 4 and adidas Adizero Evo SL sit in different categories but share a similarly bouncy midsole character. The Saucony is a true super shoe built for racing, with a full carbon plate and a slightly lighter build that gives it a more race-focused edge. It also feels impressively stable for a super shoe, which helps keep things controlled when you're pushing hard. The adidas is an uptempo trainer with premium features, including a partial plastic shank, and while it's almost as lightweight, it leans more toward versatility. Its midsole feels a bit more absorptive, making it easier to use across a broader range of training. If your goal is peak race-day performance, the Saucony holds the advantage, but if you want a lively, adaptable partner that can handle steady runs without being limited to race day, the adidas makes more sense.
