Does more stability mean more distance?
Ahead of the launch of Spieth 4 GTX, we were invited by Under Armour to elite coach Dan Whittaker’s state-ofthe-art facility. We tested it against as many competitors as we liked, using Trackman and special force plates to see if stability translated into yards.
What is stability?
Stability refers to the movement of the feet. Specifically, we were looking at vertical ground force – the force you put into the floor, measured as a percentage of your body weight. For most golfers, when your feet are moving less – are more stable – through impact, they should be able to deliver the club back to the ball faster and on a more consistent basis.
The results
We tested numerous models of golf shoe – soft and rigid, spiked and spikeless – with a 7-iron. While other factors like fit and grip configuration play a part, generally we found the wider and more rigid the outsole was, the more force and clubhead speed we created and the better control we had of strike and direction, leading to longer carries on average.
The Spieth 4 GTX and Footjoy Tour X were the best overall performers. From best to worst, we saw average variances of 7.5 yards in carry distance, 2mph in clubhead speed and 13 yards in dispersion. While some golfers like their shoes to feel soft and light, we found there is a trade off to be had. We were surprised at how different shoes produced tangible performance gains, something golfers should consider.
Bettinardi HLX 3.0 wedge
A rounded profile at address, but checks the ball up nicely and many will like the feel of the corded Lamkin grip. Price £169

Surprisingly comfortable and fits really well. We like the neutral, modern styling, but the label under the tongue is annoying! Price £54.99
