G/FORE MG4+ O2 Golf Shoe Review: Setting The Standard For Comfort On The Golf Course

G/FORE has already proven through their growing collection of releases that they make some of the best golf shoes money can buy. The Gallivan2r and G/FORE MG4+ O2 G/Lock really impressed us during testing, which makes their latest release, the spikeless MG4+ O2 version of that same shoe, even more exciting. I took them onto the Championship Links at Royal County Down to see if they matched my lofty expectations.

I'll begin by talking about the looks on offer here. G/FORE have been known for their rather bold designs in recent years - their G.112 and G/18 shoes come to mind in this regard, boasting some rather eye-catching colorways which, in all honesty, I haven't been madly in love with. However, pulling the MG4+ O2 shoes out of the box and seeing the Pumice and Chalk White colorway, I was sold.

The styling is the perfect encapsulation of the modern golf shoe. The molded external heel provides a sporty look and a home for the G/FORE logo on the exterior whilst also giving the platform for unbelievable comfort - something I'll get on to later. Each pair also comes with two pairs of laces for you to choose from, allowing for extra color coordination opportunities.

There was good news and bad news from the first round of testing - it rained heavily for the opening three holes. This meant that I got soaked, but those conditions were perfect for testing the grip of the spikeless MG4+ O2s. I'm pleased to report the lightweight, water-repellent performance upper did its job and my feet remained dry despite the conditions. Due to the wet conditions under foot, the T.P.U sole that features what the brand call their Heel-to-toe Sawtooth Traction meant I didn't slip once.

MG4+ O2 Spikeless delivers the same performance as its G/LOCK Softspike counterpart, the only difference being they are designed without the removable Tour Flex Pro Softspikes for the contemporary golfer. It really was very impressive.

Now onto the star of the show with so many of the best G/FORE golf shoes - the comfort. I've reviewed some fantastic spikeless golf shoes that provide plenty of comfort. The Under Armour Phantom Fore and Duca Del Cosma Foro come first to mind. Although those were both very comfortable experiences, the unique ribbed insole with the MG4+ O2 and other G/FORE shoes sets the standard for comfort in the golf shoe market.

We've spoken about it in previous reviews but I simply have to reiterate how enjoyable the walking experience is. If you're starting to ache and tire toward the end of the round, simply wiggle your toes or move your foot around in the shoe, and you can get a nice little massaging sensation. The insole is enhanced further by the Performance Mesh Lining that adds breathability as well as the Moulded External Heel Counter that keeps your heel where it needs to be during the golf swing whilst also providing comfort to the firmest part of the shoe.

If I offered advice to anyone considering these shoes, I’d recommend going one size larger than usual, especially if you have wider feet. I found the fit rather narrow and I have rather slim feet so I can only imagine it could prove a tighter squeeze for those with wider feet.

All in all, these shoes are a shoe-in (no pun intended) to be one of the best spikeless golf shoes of 2025. Top level performance is matched by a slick but not outlandish design that will look at home on any golf course. The durability of the materials and grip provided despite the absence of spikes means the MG4+ O2s are also an option as one of the best winter golf shoes and can prove a reliable option for players who play all 12 months of the year.
