Gel Kayano 32 vs Glycerin GTS 21

The Gel Kayano 32 is Asics at its most dependable: a premium stability running shoe built for racking up everyday miles in comfort rather than chasing pace. It is a support shoe, but a modern one. Instead of a hard medial post pushing back at your arch, it leans on soft cushioning and a guidance-led geometry that gently keeps your foot tracking straight as you tire. At a 8mm drop it sits in classic daily-trainer territory, and the plush heel makes it forgiving for heel-strikers logging long, steady runs. At 305g it is on the heavier side, so this is a comfort and protection shoe first, not a quick one. The trade-off for that smooth, planted ride is an RRP of 180 pounds, which makes it one of the dearer daily trainers out there. If you overpronate mildly and want a cushioned shoe that holds together for months of training, it earns its keep. If you want the same softness without the support, the neutral Gel Nimbus 28 is the sibling to look at. Coming from the Kayano 31? The 32 is a refinement, not a reinvention.

The Glycerin GTS 21 is Brooks' plush daily training shoe with a layer of gentle support built in. GTS stands for Go To Support, so this is the stability sibling of the neutral Glycerin 21: same soft, high-cushion ride, but with guide rails that quietly hold your stride together when your form starts to wobble. At 289g with a 10mm drop, it is a substantial, protective running shoe rather than a light or fast one. That weight is the price of the cushioning, and it is aimed squarely at runners who value comfort and a bit of guidance over speed. We rate it as a soft-riding stability daily trainer for easy miles, long runs and everyday base training. If you overpronate mildly, want a max-comfort shoe that keeps you aligned, and are not chasing pace, it is one of the easiest shoes in this class to just put on and run.
