Despite some minor issues with styling and keeping them clean, Under Armour’s Spieth 3 shoe performed as well as any other shoe on the market last year.
The new Spieth 4 GTX continues to deliver tangible performance gains. In addition to the Gore-Tex, the new heel section is manufactured from plastic, which supplies much more security.
Consequently, the weight has increased to just under 400g, so it might not offer that ultra-lightweight feel that some golfers seek, but we didn’t find them too cumbersome.
Under Armour Spieth 4 GTX Shoe Review: Performance
To ensure this shoe performs while also being comfortable, Under Armour goes to great lengths when it comes to design and testing. It is immediately noticeable how soft the Dual Durometer EVA footbed is. With just a few steps, you feel surprisingly low to the ground for a cleated shoe, and while walking between shots wasn’t stressful.
During testing on special force plates, the Spieth 4 GTX consistently came out on top among multiple competitors in terms of generating the most vertical ground force and then converting it into additional distance and speed through better control of strike and clubhead delivery.
In some cases, we saw gains of over 10 yards with a 7-iron, even against other cleated models, and the shoe was always top or very close in terms of dispersion.
I liked how the lower profile of the RST 2.0 cleats helped keep my feet on the ground for longer during the swing, harnessing maximum power from the ground.
Under Armour Spieth 4 GTX Shoe Review: Design and Features
With regards to styling, the microfibre upper, breathable and made with Clarino fibers, features subtle design patterns and bright orange accents that add shelf appeal. It is only available in one colorway, a neutral white, which is suitable for many outfits.
Despite how easily these fabrics collect dirt, the staggered entry points on the laces each help create a tight fit, pulling the shoe tightly over the foot.
Thankfully, the triangular tongue shape remains from Spieth 3, providing better coverage, but could have been thicker as it tended to dig into the top of the foot.

|Affordable||Not too lightweight.|
This golf shoe is unquestionably the most stable and effective shoe on the market, and slightly ahead of its time. Despite their comfort and softness, soft shoes do not provide the same level of support needed to swing with maximum power and control.
