Brooks Glycerin GTS 23 vs ASICS Gel-Kayano 33

Glycerin GTS 23 or Gel-Kayano 33? Here’s how they compare on feel, fit, brand specs and price, from the fitting team at The Run House.

The short answer

Want premium cushioning with gentle GuideRails support? Get the Glycerin GTS 23.

Want comfort-first stability? Get the Gel-Kayano 33.

Get the Glycerin GTS 23 if

On the run

Glycerin GTS 23: Plush, premium stability. Cushioned but surprisingly firm and dense, like the Glycerin 23, with GuideRails that guide without feeling restrictive. It feels softer walking than running.

Gel-Kayano 33: Comfort-first stability. Soft on landing at easy paces, with support that’s more gentle guidance than correction and a stiff, steady forefoot. It feels best slow, and at running pace some runners find it flat.

The Glycerin GTS 23 hasn’t been lab tested by RunRepeat yet, so its feel ratings are estimated from the Glycerin 23 lab test (same DNA Tuned foam), RTINGS’s lab test and Doctors of Running’s review.

Fit

Glycerin GTS 23. Runs slightly short, so consider a half size up. Wide and extra-wide available.

Gel-Kayano 33. True to size. The toebox tapers on the little-toe side, so it suits normal-width feet. Plush heel and tongue. Wide available.
