What we say...
Under Armour Spieth 5 SL golf shoe “changes what golfers can expect from spikeless footwear performance.”
Putting data driven design and performance above all else, Under Armour’s fifth iteration of three-time Major champion Jordan Spieth’s signature golf shoe has the comfort and feel of a spikeless, with all the traction and power of a spiked model.

Through the brand’s own innovation in spikeless outsole construction – and the introduction of a “Fourth Dimension of Traction” – golfers will be convinced they’re still wearing spiked shoes with the same comfort and incredible traction, even in wet weather. The shoe is also fully waterproof and comes with a two-year guarantee.
Developed in conjunction with leading bio-mechanist, and foremost authority on the foot’s behaviour during the golf swing, Jean-Jacques Rivet, Under Armour has built its own proprietary traction technologies – Rotational Resistance in 2016 followed by Horizontal and Vertical Traction in 2019.

This fourth dimension of traction – Interior Traction – is achieved through the introduction of a new 3D moulded footbed that features an additional wrap over the medial side and top of the foot.
This wrap eliminates ‘gapping’ between your foot and the shoe from the inside to create a fit that is tailored to your specific foot shape, reducing undesirable movement through Internal Traction.

The new spikeless outsole design uses a durable and lightweight TPU with injected rubber spikes in specially targeted areas so players will feel no shortage of traction through the golf swing.
Crucially the outsole also features flex channels that tap into valuable performance insights from biomechanics to increase traction, stability and the ability to transfer power from the ground into the swing.

This is most notable in the forefoot where Under Armour redesigned its existing flex channels to decouple the big toe, allowing it to remain grounded longer into the swing and providing a major source of enhanced stability in the golf swing.
Comfort is a given, thanks to the use of a full-length application of Under Armour’s proprietary UA HOVR cushioning platform, giving golfers comfort and energy return for the swing, while keeping as low to the ground as possible, just as Spieth himself asked for.
What Under Armour say about the Spieth 5 SL Golf Shoe
Jake Haley, Sr PLM Golf Footwear said, “By bringing a Fourth Dimension of Traction to Spieth 5 SL, we are unlocking an entire new world of product performance. This coupled with our brand-new approach to spikeless outsole construction has enabled us to truly maximise the capabilities of spikeless performance to the golfer.
“Data from our extensive testing with the world’s leading bio-mechanist, JJ Rivet, and JJ’s own expertise highlighted five areas of the foot that required activation to create the perfect fit – we call these the ‘Five Senses’.
“In Spieth 4 we were able to bring the shoe closer to the foot and engage four of the five senses of the foot. In Spieth 5 we now engage all five senses of the foot, meaning your foot is in total unison with the shoe throughout the swing.
“Put simply, Spieth 5 SL changes the game for what golfers can expect from spikeless footwear performance.”
