Drivers Sole

Drivers work on the weekend, too! Don’t slack off in the shoe department on your days off. If you want to keep it casual on the weekend, then a pair of drivers will work well for variety of plans. Whether you’re running errands or meeting up with friends, drivers are a practical and stylish choice. Looking for more outfit inspiration? In the previous chart we saw that the center of gravity for the majority of drivers is located below the center of the face, but none of the drivers measured has a CG on or below the neutral axis. With some weight positions less than 1mm from the neutral axis, Mizuno’s JPX-850 has the lowest CG of any driver measured, and likely the lowest CG. Sole: noun the undersurface of a foot. The part of an item of footwear on which the sole rests and upon which the wearer treads. ‘That sole voice belonged to the International Critical Incident Stress Foundation.’ ‘The sole purpose of this particular effort is to identify undecided voters for follow-up contact.’ ‘And the Physicians Committee for Responsible Medicine says that caloric restriction is the sole instrument that produces weight loss.’.


Drivers Sole

Through Hand Select and Bending Service, these driver heads can be ordered in

any loft from 8* to 16* in half degree increments

any lie angle from 4* upright to 4* flat of the 59* lie design spec.

any face angle from 4* open to 4* closed from each model's face angle design spec.

No driver in the world can offer such a wide range of all three key specifications on the same head, all together.

Driver lie angle is the angle in degrees between the centerline of the hosel and the ground line when the ground line is in contact with the center of the sole from heel to toe.

Most golf companies publish their lie angles, for each model of driver head, on the internet, but a simple protractor out of your tool box will do. Place your driver so that the sole is flat on the floor, rest the club against the wall, and measure the lie angle. Most drivers are between 56 and 60 degrees, and obviously the pros get theirs custom built to their specs. As a little humor here-try asking that commissioned salesmen at your big box golf store, what the lie angle is on that special driver he is trying to sell you. Watch his facial expression as he panics.

Not that long ago a standard driver lie angle was 50 degrees. In the last few years...manufacturers have raised the lie angle standards on their drivers. Tour players generally use flatter than the standard clubs that come to market, but not by much.

A quick search through the Internet (Dec.09) revealed some interesting specs. Here is some of what we found: TM R9 59D lie, Callw. FT10 58D lie, Ping G15 58D lie, Tit. 909DComp. 59D lie, Tit. 909D3 58.5D lie, Nik. SQDmo2 59D-63D, Wils. Smooth 58D lie, Adam Speedline 58D lie, Wishon 919Ti 58D lie. Obviously, with driver lies all around 58 degrees, the golf gurus have come to the conclusion that driver lie isn’t too important.

Bet You Didn’t Know: Hockey Stick Lies: 4 - 137°, 5 - 135°, 5.5 - 134°, 6 - 133°, 7 - 131°

In Fitting:

Driver lie angle is not a huge factor to worry about in fitting because:

1. Modern titanium heads cannot be bent to alter the lie angle without special equipment and heat damaging the head. As above, Wishon drivers can be bent to specific lies.

2. Shot misdirection from the lie of your head being tilted at impact is directly proportionate to the loft. Drivers have the least amount of loft of all club heads, so that the amount of misdirection is small.

3. Lie is only important to tall or short golfers because the lies on the drivers available are really tailored to male golfers of 5’11” to 6’. Obviously if you can’t get or afford to get, a driver lie custom made for you, or can’t get it bent, cut your driver down in length, to achieve a more perfect contact.

Since the lie angle of a golf club at rest is somewhat different than at impact, it is important to make a dynamic measurement of this parameter as the club contacts the ball during the swing. Centrifugal force of the moving club head will flatten the normal lie angle at the point of impact. Up to 2 degrees of change can occur by the downward bowing of the shaft. For this reason, a dynamic measurement at impact is the only accurate way to gather lie angle data.

In Conclusion:

Driver Lie angle is not much of a fitting factor in your driver because the lower loft of drivers combined with the greater droop of the shaft does not result in a marked misdirection tendency of the shot.

Unless the golfer’s physical size and address position are such that the normal range of lie angles and toe to heel sole radii offered on driver heads make the golfer so uncomfortable that they begin to change their set-up position and swing to a point that cause more swing errors, the common range of lie angles designed on the majority of drivers today will suffice.

Driver face progression and hosel offset are minor club head design parameters that have some affect on the direction and trajectory of your drives, but along with your driver’s sole radius, it is good to understand what they are, and what they do.

In figure 5 above, driver face progression is defined as the distance from the centerline (Red line) of the hosel bore or center line axis of the shaft, to the center of the leading edge (Green line) at the bottom of the face. Manufacturers of golf clubs do not provide driver face progression measurements as part of their specifications and maybe for good reason. It would only create confusion amongst consumers; however, with the advent of hybrids, the measurement may become a common specification some day to further describe these heads.

Conventional driver face progression is measured in millimeters and usually ranges between 14 to 21 m.m. It actually has a bearing on two important and different aspects of shot performance.

1. The orientation of the face at impact for possible accuracy improvement

2. The forward bending of the shaft coming into impact for possible trajectory change through the change in distance from the center line of the bore to the center of gravity in the head.

During your back swing the face of your driver is actually some 90 degrees open and as you come down to the ball (your downswing) you are trying to return the face to square. Quite difficult for most of us amateurs. Because the club face is being rotated back from open to square on the downswing, if the face of the driver is actually behind the hosel, this gives the golfer a split-second more time to continue rotating the face back around from open to square. As a result, this is how driver face progression is able to exert some influence on the orientation of the face at impact, and from that, have an effect on the accuracy of the shot. Therefore, the less face progression measurement, the more help is given to the golfer. Which of course leads us to the hosel offset driver.

As you can see in this image, an offset driver has very little face progression in m.m.

Hosel offset is defined as the distance from the forward wall edge of the hosel to the leading edge at the bottom of the face.

Many club makers think only of Face Angle as a fitting specification for helping reduce a slice or fade with drivers. Face angle can be the most effective antidote for misdirection because it can be selected in ever increasing increments of degrees of the closed face angle. However, recommending driver heads for the golfer who slices the ball which is designed with an offset hosel can be another very effective way to reduce the golfer’s tendency to slice or fade the ball. In the case of the more severe slicer, a combination of a head with an offset hosel and a more closed face can act as a double whammy of improvement. Don’t rule out trying these offset heads, as you can usually see an immediate improvement.

Sole radius is a single term that describes the amount of curvature on the sole of the driver head primarily in the direction from the heel to the toe side of the sole. While there is a slight face to back sole radius on most driver heads, it is very slight (almost flat but not quite) so the leading edge of the face is only slightly raised off the ground.

The only function of the toe to heel sole radius on driver heads is to allow a relatively smaller area of the sole to glide over the turf so as to not cause the entire toe to heel width of the sole to drag or catch the turf. Since 99% of driver hits are off of a tee, sole radius does not have much effect on the shot. Only in the rare case of a golfer trying to hit the driver “off the deck” would the sole radius of the 1-wood have a bearing on the success of the shot. Where it comes into play the most in club head design is in your fairway woods, for obvious reasons, of hitting these woods off the ground.
