Hoka Speedgoat 6 GTX Review

The Hoka Speedgoat series is a legend among trail running shoes, known for its reliable, versatile performance, excellent traction, and cushioned comfort for all mountain trail and ultra running.

The Hoka Speedgoat 6 GTX version of the Speedgoat 6, one of my favorite trail running shoes this year, adds weatherproofing to the mix, but does it compromise the flexibility and nimble-nature or the original model?

After testing both versions across varying conditions, I’ve got some insights to share. Buckle up, this review may surprise you (if you know me well enough)…

Key specifications

• Price: $170 at Hoka.com / £160 at Sportsshoes.com (UK)
• Weight: 10oz / 283g (size US M9, GTX version) – the standard version weighs 9.4oz
• Drop: 5mm (heel: 40mm, toe: 35mm)
• Upper: Waterproof GORE-TEX membrane
• Outsole: Vibram Megagrip with 5mm lugs
• Best for: Wet, muddy trails and variable weather conditions

The GTX model maintains the Speedgoat 6’s Vibram outsole and CMEVA foam midsole but introduces a waterproof GORE-TEX upper, designed for wet, muddy trails, and unpredictable climates.

How they fit and feel

The Speedgoat 6 GTX fits snug, similar to the standard version, but with less flexibility and breathability due to the GORE-TEX layer. With that said, make sure you size up a half size.

The extra stiffness is noticeable during longer runs, and while it keeps water out, the tradeoff is a warmer and tighter fit, especially in hotter conditions. For those used to the lighter, airier feel of the non-GTX model, this will feel like a step down in comfort. Added to that is a tongue that is rigid, locked in place, and still too short.

What’s good

The upper with GORE-TEX’s Invisible Fit waterproof membrane is obviously one of the stars of the show here. In wet and muddy trail conditions, it does a great job of keeping your feet dry. It also has the same articulated heel counter that I love.

The GTX version maintains the same midsole and Vibram Megagrip outsole as the original which means it still gives you confidence on rocky, technical terrain and slippery surfaces.

The CMEVA foam midsole still delivers durability and responsiveness, whilst maintaining a stable and cushioned ride. Even with the stiffer upper, the shoe performs well over long distances, making it a solid option for ultra-distance trail runners facing inclement weather – just make sure you get sizing right.

What’s not so good

The weight gain over the original isn’t really noticeable but the stiffness is. This rigidity comes from the GORE-TEX upper – and sadly, for me, this detracts from the Speedgoat’s nimble feel, that I love so much.

This will almost certainly be a dealbreaker for runners who prioritize speed or flexibility over weather protection – if not, then go with the standard version.

While the GTX membrane does a great job of keeping water out of the shoes, it does trap heat during extended efforts, especially in warm or humid climates. For hot-weather trail runs, the non-GTX version remains the better choice, for sure.

Finally, the tighter fit will not suit everyone either – if you have wide feet, then go with the ‘wide version’ for sure. And if you prefer thicker socks you may find it too restrictive, but i think you should be able to get a nice fit if you size up properly – either way, I recommend trying them on before committing.

My verdict

The Hoka Speedgoat 6 GTX is a solid trail running shoe for runners who frequently face wet or muddy conditions and don’t mind breaking their shoes in. Its waterproofing, traction, and durable, balanced cushioning make it an excellent choice for technical, all-weather runs.

However, the added stiffness, weight, and reduced breathability limit its versatility compared to the non-GTX version, in my opinion.

If you’re tackling variable weather or regularly find yourself slogging through puddles or deep mud, the GTX will have your back. But if lightweight comfort and breathability are higher priorities, stick with the standard Speedgoat 6 – it’s still the GOAT for most conditions.

If you ask me which I prefer; 100%, the original. It seems Hoka has managed to keep the Speedgoat series a polarizing trail running shoe – and this time I’ve shifted to the other side.
