Brooks Ghost Max 4 Review: The Full RunMorph Breakdown

The Brooks Ghost Max 4 arrived in France on July 3, 2026, carrying its maker's message: make running more accessible through rethought maximum cushioning. The fourth generation of the Max line launched in 2023, it gets nitrogen-infused DNA LOFT v3 foam, sheds 28 g compared with the Ghost Max 3, and features the GlideRoll Rocker for assisted transitions. At €160, it puts Brooks squarely in the premium max-cushion segment that Nike, ASICS and Hoka split between them.

Brooks Ghost Max 4: Brooks' max-cushion daily trainer that promises effortless transitions

RunMorph Coach's tip: if you already run in the Brooks Ghost 18, the Ghost Max 4 is a noticeably more comfortable option with 10 mm of extra stack height at the heel, for roughly 30 g more. If you want a road max-cushion shoe to compare it with, the Brooks Glycerin Max 2 sits one tier above in cushioning, at 50 g more and €180.

Objective technical specs

Who is the Ghost Max 4 for?

High-mileage daily runners after maximum comfort

The Ghost Max 4 is built for runners logging 50 to 80 km a week on the road, at paces slower than 5 min/km for most of their sessions. The 40 mm heel stack and DNA LOFT v3 deliver more shock absorption than almost anything Brooks makes outside the Glycerin Max. If your legs suffer at the end of long runs, the extra cushioning of the Ghost Max 4 over the Ghost 18 is noticeable within the first hour.

Runners in rehab or prone to ankle and calf pain

This is one of the uses testers mention most often, and the design of the GlideRoll Rocker backs it up. This assisted transition system reduces how far the ankle has to flex during the roll-through, which mechanically lowers the load on the calves and Achilles tendons. For runners coming back from tendinopathy or chronic calf pain, that's a serious argument, alongside medical advice.

Orthotic users and wide feet

Brooks specifically increased the interior volume of the Ghost Max 4 to fit orthotics without compromising lockdown. The sole base is wider than the Ghost 18's, which improves passive stability without relying on a pronation-control system. For D-width feet or wider, this setup is clearly more comfortable than most neutral shoes on the market.

DNA LOFT v3 and GlideRoll Rocker: cushioning under the microscope

DNA LOFT v3 is the third generation of Brooks' nitrogen-infused foam, distinct from DNA Flash (used in trail shoes) and DNA Tuned (used in the Glycerin Max). Compared with v2, v3 saves about 28 g thanks to a lighter EVA matrix formulation, while keeping the cushioning density the Max line is known for. Energy return isn't its strength, and the Ghost Max doesn't try to be responsive, but pure comfort at easy to moderate paces is excellent.

The GlideRoll Rocker is a sole geometry that creates a natural rocking motion from foot strike to toe-off. Its curve is optimized to ease the roll-through without you having to actively fire your calf on every stride. That reduces strain on the posterior chain of the leg, which explains why the Ghost Max is often prescribed in return-to-run protocols after injury.

With 40 mm at the heel and 34 mm at the forefoot for a 6 mm drop, the Ghost Max 4 sits above the Brooks Ghost 18 (36/26 mm, 10 mm drop) and below the Glycerin Max 2 (45 mm max stack). It's the sweet spot if you want plenty of cushioning without going to extremes.

Ghost Max 4 vs Ghost 18 vs Ghost Max 3: the comparison

The step from Ghost Max 3 to 4 shows up mostly on the scale: 28 g saved thanks to DNA LOFT v3, the same foam as the Ghost 18 but in a higher-stack setup. The GlideRoll Rocker is tuned for an even smoother transition. Stack height, however, is unchanged between the 3 and the 4: raw cushioning doesn't go up.

Ghost Max 4 vs the road max-cushion competition

The Ghost Max 4 lands in a crowded segment. Against the Hoka Clifton Pro, its most direct rival at the same price, it's 24 g heavier but offers a roomier fit and a gentler drop. Against the Asics Gel-Nimbus 28, it's €40 cheaper at a comparable weight. The choice mostly comes down to fit: Brooks is known for its natural, wraparound fit, Hoka for a snugger upper.

How to fit the Ghost Max 4 into your RunMorph training plan

The Ghost Max 4 is the shoe for easy runs, recovery runs and long runs at a controlled pace. In a structured plan with 4 to 6 sessions a week, it should ideally cover 60 to 70% of your mileage, at paces between 5 min/km and 6 min/km. For intervals, tempo or marathon-pace sessions, a lighter, more responsive shoe is the better call.

Its specific strength is active recovery: after a race, a heavy long run or a hard session, the Ghost Max 4 reduces the mechanical load on your muscles and tendons and lets you keep running volume up even during recovery phases.

RunMorph Coach's verdict

The Brooks Ghost Max 4 is a welcome update on one critical point: weight. Shedding 28 g on a max-cushion shoe was necessary to stay competitive against a 268 g Hoka Clifton Pro and max-cushion rivals that keep getting more refined. The optimized GlideRoll Rocker improves transitions and justifies its specific use for runners with calf or ankle issues. The max-cushion segment has become extremely contested, and the Ghost Max 4 holds its own there with real credibility, without being revolutionary.

If you want maximum comfort, a roomy fit and assisted transitions for €160, the Ghost Max 4 is a solid choice. Score: 8/10.

Key takeaways for your training

• DNA LOFT v3: 28 g saved over the Ghost Max 3, with no compromise on perceived cushioning.
• Optimized GlideRoll Rocker: assisted transitions that reduce load on the calf and ankle, useful in rehab.
• 40/34 mm stack, 6 mm drop: more cushioning than the Ghost 18 (36/26, 10 mm drop), less than the Glycerin Max 2 (45 mm).
• Roomy, orthotic-friendly fit: designed to take orthotics without losing lockdown.
• Easy runs and recovery: don't use it for intervals or fast paces, that's not what it's built for.
