Our Verdict
ASICS S4+ YOGIRI
ASICS YOGIRI SPEED
The ASICS YOGIRI SPEED has several meaningful improvements over the ASICS S4+ YOGIRI. The YOGIRI SPEED is a bit lighter, despite being higher-stacked and having better cushioning. It's a worthwhile upgrade, although the ASICS S4+ YOGIRI is still a good shoe if you can find it at a discount.
