Asics Gel-Nimbus 27 vs Asics Novablast 5

Same brand, two different ideas of comfort. In one corner, the Asics Gel-Nimbus 27 , the max-cushion flagship that protects every step. In the other, the Asics Novablast 5 , the bouncy daily trainer that made high stacks feel fun and fast.

The Nimbus 27 stands for premium protection: FF BLAST PLUS ECO foam with PureGEL cushioning, a towering 44mm heel stack, a soft jacquard mesh upper, and Hybrid ASICSGRIP rubber built for long miles and long days. The Novablast 5 stands for lively versatility: FF Blast Max foam with a trampoline-inspired geometry, a light 254-gram build, and a ride that works for easy days and tempo days alike.

So which Asics deserves your money — the plush protector or the bouncy all-rounder? We have analyzed every detail, from foam compounds to customer reviews, comparing cushioning, weight, fit, and value to pick a clear winner.

Comfort & Fit

Comfort is the whole debate here. One shoe swaddles your foot, the other launches it forward.

Round Winner: Asics Novablast 5

The Asics Novablast 5 wins this round because its comfort works at every pace. The FF Blast Max midsole with a trampoline-inspired geometry returns energy instead of just absorbing it, and at 254 grams it stays light enough for daily miles, long runs, and even tempo work. Break-in is zero — comfortable from the first step. As one owner put it, the plushness and bounciness deliver a trampoline effect after every step, and another called them almost the best running shoes ever worn, very light with a lot of cushion.

Fit is true to size with a medium-to-wide, roomy toebox that normal and wide feet love; narrow feet should use snug lacing or the gusseted tongue to lock down. The engineered jacquard mesh breathes well. The real trade-offs are wet traction, which is poor on slick roads, and some reports of sole peeling and toebox wear with heavy use.

The Asics Gel-Nimbus 27 is softer on slow miles and tougher in bad weather. The FF BLAST PLUS ECO foam with PureGEL sits under a massive 44mm heel and 36mm forefoot, wrapped in a plush jacquard upper with a knit tongue and collar that feels premium from step one. At 306 grams it rides heavy and dull when you push the pace, and a few runners report numb toes or blisters if the fit is off. But for easy days, recovery miles, and standing all day, it is superb. One reviewer called it an absolute workhorse, smooth and great as an easy-day shoe, like walking on clouds.

The Novablast takes the round because it gives you nearly all the daily softness with 52 grams less weight, a livelier ride, a higher 4.6 rating, and ten dollars back in your pocket.
