ASICS S4+ Yogiri Reviews

They raced their first sub-1-hour 10k in the S4+ Yogiri and loved it at 5:00-5:30/km, feeling stable and comfortable.

They use it as their long run shoe and like the rocker, upper and stability, but find the midsole firm and too hard for easy miles or speed work.

Pace decides it: at 4:30/km it shone, stable and rolling over 35 km, ideal for sub-3.5 to sub-4. Jogging at 6:00/km it feels board-like and slaps, and at 4:00/km and interval pace it gives clearly less help than a Metaspeed, so it's not a sub-3 racer. The outsole tread is still good at 300 km.

Delivers exactly what S4 stands for: speed, stability, safety and sub-4. Stability is the highlight, almost to a fault: you won't wobble, sit back on your heels or struggle to transition whatever your race pace, at a reasonable 8.1 oz and $200. The dense lower Flytefoam gives a dull, firm heel with little bounce.
