The ASICSGRIP outsole receives consistent praise for its thickness, grip, and minimal wear after significant mileage (100+ km). Reviewers note the shoe holds up well, with little visible degradation and robust build quality.
The ASICS S4+ Yogiri is positioned as a stable, carbon-plated shoe designed for everyday runners and marathoners who prioritize stability and durability over maximum propulsion. Its firm midsole and substantial ASICSGRIP outsole provide excellent traction and durability, making it suitable for daily training and long runs, especially for runners who want a more stable, less aggressive ride than elite 'super shoes'. The shoe's firmer feel and less energetic foam make it less ideal for tempo runs and racing compared to top-tier racers like the Metaspeed Sky/Edge, but it remains a practical option for non-elite marathon racing and threshold efforts. The stability and cushioning also make it a good choice for recovery runs, though the firmness may not appeal to those seeking a plush ride. The shoe is not designed for trail running due to its road-focused outsole and geometry.
Ideal for Best suited for intermediate to experienced runners aiming for marathon or half marathon distances who prioritize stability, durability, and a firmer, more controlled ride. Ideal for those training for sub-4 hour marathons, runners with less efficient form, or anyone seeking a reliable carbon-plated shoe for both racing and high-mileage workouts.

The fit is secure throughout, with a focus on stability and comfort for longer races.
Sizing: Generally true to size; designed for a broad range of runners, including those targeting sub-4 hour marathons. No widespread reports of needing to size up or down compared to standard ASICS sizing.
