Our Verdict

Saucony Endorphin Speed 4

ASICS SUPERBLAST 2

The ASICS SUPERBLAST 2 and the Saucony Endorphin Speed 4 are both versatile trainers but cater to slightly different priorities. The ASICS is an unplated, uptempo premium trainer that emphasizes maximum cushioning and provides a stable, plush ride, making it especially appealing for longer runs. The Saucony, however, is a super trainer that prioritizes a more energetic and responsive experience, featuring a bouncy midsole and a nylon plate, making it better suited for shorter races and faster workouts. While both shoes handle versatility well, the ASICS excels in comfort and protection. In contrast, the Saucony is the preferred option if you want a snappier shoe that can comfortably pick up the pace for faster efforts like intervals or tempo runs.
