Overview
The Ghost Max line has a clear job: take what the Ghost does for daily training and scale it up for runners who want more cushion and more protection without moving to a specialty stability or motion control category. The Ghost Max 4 arrives with the same DNA Loft v3 foam that powers the Ghost 18, the same GlideRoll rocker geometry that defines the Max line’s character, and a meaningful weight reduction over the Ghost Max 3 despite keeping the 40mm heel stack in place. This is not a shoe chasing trends. It is a shoe refining a formula that works, and at $165 it delivers that formula with enough consistency to justify the update.
Upper
The upper is a soft breathable mesh built on a linear last that accommodates a wide range of foot shapes without committing to an extreme width. The plush tongue and robustly padded heel collar are the Ghost Max’s most immediately noticeable comfort features; the collar in particular wraps the ankle without the rigid structure that can create pressure on longer efforts. Midfoot lockdown is secure through standard lacing. One fit note worth knowing: the Ghost Max 4 runs with meaningful volume through the forefoot and toe box, which suits runners with wider feet or those who prefer room to splay. Narrower feet may find the upper less snug than expected even when laced down; if precise lockdown is a priority, this is worth testing before committing. The toe box also reads slightly long to some runners. Sizing is true to size for most.
Midsole
DNA Loft v3 is the nitrogen-infused foam underneath, the same compound Brooks uses across several models in the current lineup. At 40mm heel and 34mm forefoot with a 6mm drop, the stack is firmly in the max-cushion category. What distinguishes the Ghost Max’s foam character from softer PEBA-based competitors is its firmness: DNA Loft v3 provides protection and absorbs impact without the deep, pillowy compression that some max-cushion shoes deliver. There is subtle energy return but not the spring or propulsive feel that A-TPU or PEBA foams generate. For runners who have found ultra-soft max-cushion shoes unpredictable or unstable on tired legs, the Ghost Max 4’s firmer character is a feature rather than a limitation. The GlideRoll rocker geometry is built into the midsole profile and works in concert with the foam to guide the foot through heel-to-toe transitions without demanding input from the runner.
Outsole
Full-coverage rubber outsole with ample contact area and reliable grip on wet pavement. Pacific Northwest runners logging miles on rain-soaked roads from October through May will find the Ghost Max 4’s outsole predictable and trustworthy; the coverage and compound hold traction on slick surfaces without the drama that partial-coverage outsoles can introduce. Durability follows Brooks’s established pattern: the rubber holds through high-mileage training blocks without significant degradation at the contact points that matter.
Performance
The Ghost Max 4 performs best at easy and recovery paces where the GlideRoll rocker and DNA Loft v3 can do their best work: smooth, effortless transitions and consistent protection mile after mile. The rocker geometry is the Ghost Max’s genuine differentiator from the standard Ghost lineup; it takes the effort out of heel-to-toe movement in a way that benefits runners logging high mileage on tired legs or those managing impact-sensitive joints. The firmer foam character means the shoe stays composed and stable through extended efforts rather than becoming wallowy as softer compounds can under prolonged loading. The Ghost Max 4 is not a shoe for uptempo work or speed sessions; the stack and foam tuning favor sustained comfortable effort, and the shoe does not reward faster running the way lighter, more responsive trainers do. As a dedicated easy-day and long-run shoe it is exactly what it claims to be.
Overall Conclusion
Brooks updated the Ghost Max 4 by making it lighter without changing what the shoe is: a firm, smooth, protective max-cushion daily trainer built around GlideRoll geometry and DNA Loft v3 consistency. Runners who want more cushion than the standard Ghost without the instability that ultra-soft foams can introduce will find the Ghost Max 4 a natural fit. At $165, it competes in a category where newer foam technologies are pushing the ceiling on what max-cushion shoes can feel like; the Ghost Max 4’s honest answer is that not every runner needs or wants that ceiling, and the formula it delivers has earned its reputation over multiple generations for good reason.
Final Grade: 8/10
DNA Loft v3 firmness paired with GlideRoll geometry makes the Ghost Max 4 the most refined version of Brooks’s max-cushion daily trainer: lighter than its predecessor, consistent underfoot, and honest about what it is built for.
