Saucony Endorphin Speed 4 vs adidas Adizero Boston 13

The Saucony Endorphin Speed 4 and adidas Adizero Boston 13 are both versatile, plated trainers that can handle everything from steady daily miles to faster workouts, but they lean into slightly different strengths. The Saucony is lighter and more energetic, featuring a softer, more cushioned heel and a more bouncy feel. Its plastic plate is a bit less stiff than the adidas' ENERGYRODS. The Boston 13, on the other hand, is built for those who prefer a firmer feel in the heel and a more connected ride overall. It's also slightly heavier than the Saucony, so overall, the Saucony is the better performer in most use cases, while the Boston 13 offers a classic, workhorse feel that's great for runners who want a firmer, more focused ride during tempo efforts.
