ASICS GEL-KAYANO 31 vs Nike Structure 26

The Nike Structure 26 and ASICS GEL-KAYANO 31 are two classic stability shoes that are among their respective brands' oldest series. The GEL-KAYANO 31 has more stability-focused design elements, including a harder block of foam in the midfoot for arch support, and a softer pod of foam on the lateral side, designed to spring over-pronators back into a more neutral position; the Structure 26 meanwhile mostly relies on guide rails on both sides of the shoe to stabilise the foot. The ASICS shoe is heavier and higher stacked than the Nike shoe, with much worse energy return.
