Our Verdict

adidas Adizero Adios Pro 4

Saucony Endorphin Elite 2

The adidas Adizero Adios Pro 4 and the Saucony Endorphin Elite 2 are both high-end super shoes that strike an impressive balance between cushioning and energy return, and they weigh about the same. The adidas offers a slightly more cushioned underfoot feel that's great for protecting legs over long distances. The Saucony, while still well-cushioned, offers a firmer, more stable ride. Both are optimized for marathon efforts, but if you had to race a 5K in one of them, the firmer platform of the Saucony would better support quick turnover and a snappy toe-off.
