I caught up with Under Armour’s Mike Forsey at the PGA Show in Orlando.
He was the man who worked directly with Spieth to create this shoe…
We worked with Jordan for about a year, looking at his on-course needs.
“Just like all the top players, he has great footwork and great balance but if there’s anything we can do for a tour player we hope it can translate and be meaningful for a recreational player.
“Jordan has a unique move to his left side. He gets to that lateral left edge of his shoe with his long irons and his driver.
“We spent a lot of time with him, following him on the course, looking at his practise sessions and he also has a simulator in his house so we filmed a lot of him there.
“We came up with a few concepts and suggested some directions to go in.
“One thing was to try and get him closer to the ground. This outsole is about as close to the ground as you can get.
“We didn’t want to put him on a platform where he gets to that lateral edge and basically falls of the shoe.
“We video taped him from the first sessions and then into this product and there’s a distinct difference from where he was.
“Now he can go after it really aggressively and he doesn’t even get to the outside edge anymore. He just rolls naturally from the top of the swing through to the finish.

So what have Under Armour done to prevent Spieth ‘falling off’ the left edge of his left shoe?
The Spieth One features what Under Armour are calling rotational resistance traction.

Different cleats and materials are used on the outstep of the shoe.
The upper of the Spieth One is composed with a single seam, reducing layers and weight.
The outsole has a softer forefoot for flexibility, paired with a firm heel for stability and support.

Under Armour Spieth One review – The results
After putting these shoes on, I soon got over the looks. I think they actually look a lot better on than off.
One thing that struck me was just how well padded they were.
It really feels like your foot has been nicely locked in. This helps raise the comfort levels too.

I wouldn’t dream of comparing myself to Jordan Spieth – I’m a much better putter for a start – but I have been known to display unusual footwork in my golf swing.
The more a shoe can keep me rooted to the ground the better.
This is exactly what I found with the Spieth One. They gave me a really sold and stable base.
I tested them out on the course at Moor Allerton in very wet and muddy conditions and didn’t suffer any loss of traction at all.
This is a really comfortable shoe and feels incredibly solid.
One slight draw back for me is the weight – they did feel a bit on the heavy side.

This was probably because I’m so used to wearing lightweight spikeless shoes so it took a while to adjust to wearing something a bit more substantial.
Under Armour Spieth One review – NCG Verdict
I’m really looking forward to wearing these shoes a bit more over the winter and I’ll probably look to them in wet conditions during the summer.
On a firm course in the middle of the summer, I just can’t see me opting for anything other than a spikeless model.
This is a premium shoe and feel like it’s loaded with tech and quality materials.
They’re not cheap but you’ll feel like you’re getting a high-quality product.
If you’re after something to add a bit more stability and traction that doesn’t compromise on comfort – the Spieth One are definitely worth a look.
