Our Verdict

Saucony Endorphin Pro 4

adidas Adizero Adios Pro 3

The Saucony Endorphin Pro 4 and the adidas Adizero Adios Pro 3 are both high-performance racing shoes, but they cater to slightly different strengths. The adidas offers more cushioning and better energy return, making it feel softer and more efficient. In contrast, the Saucony is notably more stable and features a stiffer forefoot, which helps create a dynamic, snappy ride, especially beneficial for shorter races like 5Ks and 10Ks. Additionally, the Saucony is slightly lighter, giving it a more agile feel. Overall, the Saucony is probably the better race-day option for most.
