Style and aesthetics
Comfort a fit
MG4+ O2
Comfort is one of the MG4+ O2’s strongest traits. The auxetic lattice midsole provides responsive cushioning, while the fully padded mesh interior and massaging insole deliver all-day comfort. Golfers frequently praise how “broken-in” the shoe feels straight out of the box. Fit is generally true to size, making it an easy pick for most foot shapes.
G/18
The G/18 is built for endurance. Its wide base, cushioned foam interior, and waterfall lining are designed to handle long walks and uneven terrain. However, the fit runs narrow, and many reviewers recommend sizing up, especially for wider feet. Once dialed in, comfort is excellent, but it may take more trial to get the sizing right.
Comfort winner: Tie – MG4+ O2 for immediate comfort, G/18 for long-haul support.

Stability and traction
MG4+ O2
Despite being spikeless, the MG4+ O2 holds its own thanks to a sawtooth traction pattern and an external heel counter that locks the foot in during the swing. Stability is impressive for such a lightweight shoe, though aggressive swingers may notice some limitations in wet or steep conditions.
G/18
This is where the G/18 shines. Gravitee traction delivers three levels of simultaneous grip, while the rubber toe wrap creates a reliable pivot point during rotation. The wide base and prominent heel counter give it a planted, confidence-inspiring feel, especially on uneven lies or during powerful swings.
Stability Winner: G/18 – noticeably more secure.
Waterproofing and weather performance
MG4+ O2
The MG4+ O2 features water-repellent materials, which are effective for light moisture, morning dew, or quick rounds in variable conditions. However, it’s not fully waterproof, and extended play in heavy rain may push its limits.
G/18
Built with a 100% waterproof T.P.U. upper, the G/18 is designed for serious weather resistance. Golfers have consistently highlight its ability to keep feet dry in wet, muddy, or cold conditions without sacrificing comfort.
Waterproofing winner: G/18 – no contest.
Durability and build quality
MG4+ O2
Lightweight materials make the MG4+ O2 comfortable, but they can show wear sooner, especially for golfers who play frequently or walk every round. The shoe holds up well under normal use, though it’s better suited for fair-weather golfers.
G/18
Durability is a major selling point of the G/18. The T.P.U. upper and rubber outsole are built to take abuse, and golfers often note that the shoe looks and feels solid even after months of play. It’s a true workhorse.
Durability Winner: G/18 – built for the long run.
