Mizuno ST-Z 230 Mens Golf Driver RD

Welcome to The Golf Shop Online. Since 2002, we’ve been helping golfers of all levels find the right equipment at the right price, with the service and support you’d expect from a trusted specialist.

We started with a small pro shop and quickly realised that space limited what we could offer our customers. Moving online allowed us to showcase a much wider range of golf products from the game’s leading brands, all backed by professional advice and reliable service.

Today, The Golf Shop Online is a well-established and respected retailer with thousands of happy customers. We are proud to be authorised by every brand we stock, which means every product you buy is 100% genuine and comes with the full manufacturer’s warranty.

Customer trust is central to what we do. We are rated “Excellent” on Trustpilot and Reviews.io, and we continue to focus on giving you the best possible experience — from competitive pricing and expert support to fast delivery and an easy 60-day returns policy. Our Price Promise gives you extra confidence that you are always getting genuine value.

Behind the website is a friendly, knowledgeable team led by PGA professional Mark Crossfield, who has over 330 million YouTube views sharing trusted golf advice. Whether you need help choosing the right driver, advice on custom fitting, or simply can’t find the product you’re looking for, we’re only a phone call or email away.

Thank you for shopping with The Golf Shop Online. We look forward to helping you enjoy your game with the right equipment and service every step of the way.

We believe you’ll get on well with your new driver, but if you don’t, our 60-Day Play Better Promise gives you extra peace of mind. If you’re not happy, you can return it for an exchange. This can be against another driver or for shop credit valid for six months.

To return your golf driver, simply send it back with a cover note including your GSO order number and a short explanation of why it wasn’t right for you. The cost of return postage is your responsibility, and we recommend using a tracked, signed-for service for protection, as The Golf Shop Online cannot be held responsible for returns not received.
