Brooks Glycerin 20 vs ASICS Gel Nimbus 25: Premium Cushion Battle

Overview

The Brooks Glycerin 20 and ASICS Gel Nimbus 25 are the flagship max-cushion neutral trainers from two of running's biggest brands. Both cost $159.95 and target runners who want the ultimate in plush, protective cushioning for long runs.

Cushioning Technology

The Glycerin 20 uses Brooks' DNA LOFT v3 foam — soft but with good energy return. It has a balanced, bouncy feel. The Nimbus 25 combines FF BLAST+ Eco foam with PureGEL technology (replacing the traditional gel pucks). The result is an incredibly soft landing that absorbs nearly all impact.

Ride Feel

The Glycerin 20 feels more responsive — you push off with each stride. The Nimbus 25 feels more cushioned and absorptive — it protects your joints at the expense of some energy return. Runners who want to feel the ground prefer the Glycerin; those who want maximum protection prefer the Nimbus.

Upper Comfort

The Nimbus 25 has a knit upper that's among the most comfortable in running — it fits like a sock. The Glycerin 20's engineered mesh is also excellent but slightly more structured. Both shoes have plush tongue and collar padding.

Durability

Both last 400–500 miles. The Nimbus 25's AHARPLUS outsole rubber tends to be slightly more durable on abrasive surfaces. The Glycerin's outsole wears evenly and maintains grip well.

Who Should Buy Each

Choose the Brooks Glycerin 20 if: You want max cushion with energy return. Slightly more versatile for different paces.

Choose the ASICS Gel Nimbus 25 if: You want the softest possible ride for joint protection. Best for easy runs and runners with joint sensitivity.
