Inertia Athletes

The people who feel the difference first

Our athletes and ambassadors compete and coach across the highest levels of golf. They pressure-test every pattern change before it reaches production.

Mark "Fooch" FulcherGolf — Caddie

Mark "Fooch" Fulcher

“When you walk 18 holes, seven days a week, every bit of stability in your shoe matters. Inertia gives me that quiet confidence underfoot.”

Mark is one of the most respected caddies in world golf. Best known as Justin Rose's long-time bagman, he has been on the bag for some of the game's biggest wins since the pair first teamed up in 2008. His reputation is built on calm decision-making, relentless attention to detail and the ability to keep a player grounded under pressure.

Training tip
Pre-round routine: stretch your feet and ankles the same way you warm up your shoulders. A stable base sets the tone for the whole round.

Olly BrettGolf — Caddie

Olly Brett

“Caddying is a lot of miles, a lot of slopes and a lot of waiting. I need kit that performs when the pressure is on and stays comfortable when the day is long.”

Olly carries the bag for rising PGA Tour star Michael Brennan. He is part of a new generation of tour caddies who combine sharp course strategy with a deep understanding of how equipment, conditioning and marginal gains add up to better results.

Training tip
When reading a putt, don't just look at the line — feel your footing. If your feet slip, your stroke changes; if your feet are planted, your read has a chance.

Robbie MorrisonGolf — Professional

Robbie Morrison

“I'm out here chasing fractions of a shot. The grip inside my shoe might be invisible to the gallery, but it matters when I'm swinging at full speed.”

Robbie is a Scottish professional golfer based at Kilmacolm Golf Club, where he is also club ambassador. Born in Glasgow in 1996, he turned professional in 2018 and has since played events across the globe, from Australia to the NZ PGA and the Tartan Pro Tour. A proven winner on the Tartan Pro Tour, Robbie brings the same work ethic to his game as he does to representing the next generation of Scottish professionals.

Training tip
On a links course, your footing changes with every lie. The better your connection to the ground, the freer you can swing through the wind.

Alex WalkerGolf — Professional

Alex Walker

“Every amateur asks what equipment matters most. I always start with the basics: the only thing connecting you to the club is your grip, and the only thing connecting you to the ground is your feet.”

Alex is a professional golfer competing on the Tartan Pro Tour. A dedicated student of the game, he has built his career on disciplined practice, smart course management and a belief that the smallest details often separate the field.

Training tip
Range work: before you hit balls, hit five shots with your full attention on how your feet feel at address. Ground awareness is the first step to balance.
