Asics Gel-Nimbus 28 vs Asics Gel-Kayano 33:
Which to Choose

The single biggest difference is support: the Nimbus 28 is a stable-neutral trainer — a wide max-cushion base that steadies the ride without any correction — while the Kayano 33 is a true stability shoe, using Asics' 4D Guidance and FluidSupport to actively manage mild-to-moderate overpronation. If your gait is neutral, the Kayano's guidance can feel like more structure than you need; if you roll inward, the Nimbus won't give you the control the Kayano does. Cushioning-wise the Nimbus sits taller and softer, with a 40 mm heel / 34 mm forefoot stack of FF Blast+ over a PureGEL heel insert that smooths heel-first landings into a very gentle touchdown. The Kayano is a touch lower and firmer underfoot at 37 mm heel / 28 mm forefoot, pairing a soft FF Blast Max top layer over a firmer FF Blast+ base — plush on first step but more planted and controlled through the transition. On weight and drop, the Nimbus is the lighter and lower shoe at 278 g (men's US 9) and a lab-measured 6 mm drop, versus roughly 298 g and an 8 mm drop for the Kayano, so the Nimbus feels a shade nimbler and lower to the ground while the Kayano rides a little more workmanlike with a higher heel ramp. Neither has a plate and both offer moderate, pleasant-rather-than-propulsive rebound, so both fade if you push toward tempo — the Nimbus's fastest effective zone lands around 5:15–5:45 min/km and the Kayano around 4:45–5:00 min/km. Use case tracks that: both handle 10K and half comfortably, but the Kayano's supportive geometry extends its sweet spot out to marathon-distance mileage, while the Nimbus is happiest as an easy-and-long comfort cruiser.
