Ever glanced at a driver in a golf shop, seen the letters SFT, and had no idea what it meant? You’re not alone. This little acronym often stands for Straight-Flight Technology, a design philosophy that club manufacturers use to help golfers hit the ball, well, straighter. This article will break down what SFT means for your equipment, how the technology works its magic, and most importantly, how you can apply the same core principles to your swing - with or without a new club - to find more fairways.

What "SFT" Really Means: Straight-Flight For The People
At its heart, "SFT," or Straight-Flight Technology, is a manufacturer's term for a club - usually a driver or fairway wood - that is specifically engineered to combat a slice. A slice, that pesky shot that curves dramatically from left-to-right for a right-handed golfer, is the most common miss for amateurs. It’s frustrating, distance-robbing, and can turn a good hole into a scramble for bogey in a heartbeat.
Club designers know this, so they created SFT models to provide a built-in fix. While Cleveland Golf popularized the "SFT" acronym, almost every major brand has its own version. You might see it labeled as a "D-Type" (for Draw-Type) by TaylorMade, or simply a "draw-biased" model from other companies. No matter the name, the goal is the same: to make it easier for the golfer to square the clubface at impact, reducing side spin and producing a straighter, longer ball flight.
Think of it as a friendly assist. The club is designed to help nudge the ball back toward the center of the fairway, counteracting the natural tendencies that cause a slice for millions of players. But how exactly does a piece of metal and carbon do that?

How Does Straight-Flight Technology Actually Work?
SFT isn't just a marketing slogan, it’s based on some clever physics and design tweaks that are all meant to influence the clubhead's behavior during those crucial milliseconds of your downswing and impact. Here are the main components that make an SFT club what it is.
Heel-Biased Weighting
This is the biggest and most important element. SFT clubs have more mass concentrated in the heel of the clubhead (the part closest to the hosel and shaft). This bit of internal or external weighting has a profound effect on the club's moment of inertia along the shaft's axis. In plain English, weighting the heel encourages the toe of the club (the part furthest from you) to rotate and close faster through the impact zone.
A slice is almost always caused by an open clubface at impact, meaning the face is pointing to the right of the target as it strikes the ball. By adding weight to the heel, designers make it physically easier for that clubface to "turn over" and get back to square. It’s like giving the heel side of the club a little head start so the toe can catch up, which is exactly what a slicer needs.
Upright Lie Angle
The lie angle is the angle between the shaft and the ground when the club is soled correctly. SFT models often feature a slightly more upright lie angle than their standard counterparts. A more upright club means the toe sits higher off the ground, causing the heel to lead slightly. This can subtly encourage the clubface to point slightly left at impact (for a righty), which helps start the ball further left and gives it more room to curve without ending up in the right-side trees.
Slightly Closed Face Angle
Some SFT clubs take a preemptive approach by featuring a face angle that is subtly "closed" or "hooded" at address. This means that when you set the club down, it might appear to be aiming just a tiny bit left of your target line. It's a visual cue and a physical head start designed to offset the golfer's tendency to open the face during the swing. By the time the golfer makes impact, that slightly closed starting position helps a chronically open face arrive much closer to square.
Softer Shaft Profiles
While the clubhead gets most of the attention, the shaft plays a role, too. Draw-biased clubs are often paired with shafts that have a slightly softer tip section. A more flexible tip can help the clubhead release or "kick" more actively through impact, further promoting that face-closing rotation that slicers are looking for.

With all this corrective technology packed in, it sounds like an SFT driver is a no-brainer for anyone who hates seeing their ball sail right. And for many, it is. If you're a high-handicap golfer or anyone who battles a consistent, frustrating slice, an SFT model could absolutely help you enjoy the game more. More fairways often means lower scores and less pressure.
However, these clubs aren't for everyone. Here’s a quick gut check:
Who benefits most? Golfers who consistently slice the ball and have trouble squaring the face, regardless of what they try to do in their swing.
Who should be cautious? If you already hit a straight ball or a draw (a right-to-left curve), an SFT club could be a recipe for a hook (a shot that curves too much from a right-to-left). A hook is just as damaging as a slice. Players who can work the ball both ways may also find the draw bias interferes with their ability to hit an intentional fade.
The best advice is to always try before you buy. If you can, hit the club you’re considering on a launch monitor at a store or get a full fitting with a professional. See what the numbers say. Don't just buy a club because it promises a fix, buy it because it delivers that fix for you.

Create Your Own "SFT": How to Hit Straighter Shots Without a New Club
While technology is a great aid, it's also true that SFT clubs are treating the symptom (an open face at impact), not necessarily the root cause in your swing. As a coach, I believe the most lasting way to hit straighter shots is to understand and fix the movements that create the slice in the first place. You can build your own "Straight-Flight Technology" right into your swing mechanics.
1. Strengthen Your Grip: The Steering Wheel
Your hands are your only connection to the club. If your grip is "weak" (with the lead hand, your left for a righty, rotated too much under the shaft), it's extremely difficult to close the face. Correct this first.
How to do it: When you take your left-hand grip, you should be able to look down and see at least two knuckles. The "V" formed by your thumb and index finger should point toward your right shoulder. This is a more "neutral" to "strong" position that gives your wrists the leverage they need to naturally close the face through impact.
2. Check Your Setup and Alignment
Many slicers unconsciously aim their bodies far to the left to "play for the slice." This only encourages an "over-the-top" swing path which, funny enough, makes the slice even worse. You have to break the cycle.
How to do it: Use alignment sticks. Place one on the ground pointing at your target and another parallel to it for your feet. Make sure your feet, hips, and shoulders are all set up square to your target line. This will feel strange at first if you're used to aiming left, but it trains your body to swing toward the target, not away from it.
3. Fix Your Swing Path: Stop Coming "Over the Top"
This is the number one cause of a slice. An "over-the-top" move is when your downswing starts with your shoulders and arms throwing the club out and away from your body, causing the club to travel from outside the target line to inside it across the ball. This cutting motion imparts massive slice spin.
How to do it: To fix this, you need to feel the club dropping to the inside on the downswing.
The Downswing Sequence: After you get to the top of the backswing, the first move down should be a slight lateral shift of your hips toward the target. This drops the club into "the slot." From there, your torso and hips can unwind, pulling the arms and club through on a proper in-to-out path. Let your body do the work, not your arms.
The Gate Drill: Set up a soft object (like a headcover or a towel) just outside and slightly in front of your golf ball. Set another one up just inside and slightly behind your golf ball. Your goal is to swing the clubhead through this gate without hitting either object. This will force you to approach the ball from the inside and extend out toward the target - the opposite of a slice motion.
Final Thoughts
So, SFT or "Straight-Flight Technology" is a club design that uses heel-weighting and other tweaks to help a slicer square the clubface and hit the ball straighter. While SFT clubs can be a huge help for many amateurs, the most reliable path to better golf is understanding and improving the mechanics in your own swing that cause that slice in the first place.
