Our Verdict
New Balance FuelCell Rebel v4
ASICS GEL-KAYANO 31
For most runners, the New Balance FuelCell Rebel v4 has some advantages over the ASICS GEL-KAYANO 31. It's a significantly lighter shoe that has some ground feel due to its much lower stack height than the GEL-KAYANO. Thanks to its more responsive foam, the New Balance is a bit more efficient and better at picking up the pace. The GEL-KAYANO is still a better fit for runners who prefer higher stacks or need a stability shoe.
