Primus Trail FG - A hard sole away from being a fantastic minimal trail shoe!
I tested these along with two other pairs of trail shoes, switching between each pair run after run.
The three shoes in question are the Trailtalon 290 and Parkclaw 275 GTX both from Primus Trail FG from Vivobarefoot.
I smashed a lot of miles in all three shoes on hard & soft muddy tracks, gravel paths, wet & dry sand and on the road. Here's how the Trail FG stacked up.
This was mostly because I'd already been transitioning to barefoot for a while in the Vibram KSO EVO so having a barefoot trail shoe to try out was going to be great!
I was so excited to get them on and get out in them that I hit the trail the same evening after I unpacked them.
Weight - Size 45 EU weighing in at 270g per shoe (without insole in… I weighed them myself!)
PRO5 Sole - Patented, ultra-thin, puncture resistant layer. 5x more puncture resistant than a standard sole of the same thickness.
Vegan - Produced using animal free products and processes.
Removable Performance Insole - 3mm vegan insole. Take it out to feel the ground. Leave it in for a little extra warmth.
Breathable Mesh - Synthetic multi-ply materials to deliver optimum lightweight breathability and comfort.
V-Web - Heat fused together for lightweight structure and stitchless durability.
Tough Rubber Compound - Strong, non-marking rubber compound for sticky grip and high abrasion when you need it most.
On my first run, I had in my mind that these are specifically for firm ground and Vivobarefoot stated on their website that they're perfect for any rural or urban terrain. Straight away I noticed how hard the sole was (I ran without the optional insole).
They definitely didn't feel too great on the road en route to the trail and once I'd hit the trail which was very firm mud with rocks I thought, "Ha! This should be great!"... But it just wasn't. The Trail FG is so hard.
They didn't feel much better on gravel or groomed trail and then they didn't grip at all well on the mud at the end of the trail, I was left wondering what these shoes were good for. I was gutted.
I persevered with them though and once I'd run about 20 miles, the soles softened slightly and I finally found the perfect ground to run these on.
Not exactly firm ground but over dry muddy ground scattered with tree debris and full of roots, they were great! Though it is a bit disappointing that you need to run on such specific ground for these trail shoes to fully reach their potential.
I have to wonder why Vivobarefoot took the step of splitting their trail shoe into two for their new range.
There is a tough rubber bumper that comes up around the toe that is very rugged. It does well to protect against stubbed toes on rocks and roots.
I certainly didn't come away with any injuries after hitting rugged terrain. The sole albeit very firm is fantastic as stopping anything sharp from stabbing through the soles of your feet.
The Trail FG isn't anywhere near as inflexible as the Inov-8 Parkclaw 275 GTX but they're not that much better than the Trailtalon 290 which is surprising seeing that the Trail sole is only 5mm thick.
It should be incredible but it really does feel very stiff when on.
I went for my usual size 45EU in these trail shoes but they came up pretty small. I really wish I went at least a size up with these because I felt as though that put an instant downer on my experience with them.
There are some positives in the design however and as much as I still don't think these shoes are for me, I can't really fault the design (too much).
The mesh upper is super light and flexible. It gives plenty of wiggle room for toes! The rubber bumper works well, but because I could have done with going a size up this was less comfortable than a soft toe would have been.
The heel cup is much more firm than that of the Stealth II. It hugs the back of my feet snugly and provides good support in that area.
The quick lacing system works quite well, however, I found that after I'd taken the Trail FG off after a run, the next time I put them on again the laces were incredibly tight around my foot.
This isn't a massive issue but because the laces are so slippy they did do this every time. I swapped the quick laces out with the spare set of standard laces the shoes came with and it helped to stop this a bit though not completely.
It's not the end of the world but it's frustrating having to find the perfect lace tension every single time I put them on rather than just slipping them on and doing them up.
Grip wise they did OK. They're not bad on the road and dry muddy ground.
They also do pretty well on the beach. But on slippy grass, mud or slimy rocks and/or pavements they're a bit scary!
They really shone on soft-ish, dry muddy ground. The sort you get beneath a treeline in the spring.
They ate it up and the runs I took the Trail FG on with this terrain were some of the most enjoyable I've been on in recent months. I just really wish all of my runs in them could have been the same.
As I mentioned above, the heel cup on these shoes offers good support for my feet. When laced in I felt locked in!
But as with the Stealth II, these shoes plan to allow your feet to act for themselves and don't really offer a load of support.
They don't do it as well as their super comfortable road brother but they do try to let your feet work things out for themselves which for me is the best sort of support available!
It may seem as though I dislike the Primus Trail FG but it's not at all bad. It doesn't suffer from the momentum killing factor that the Inov-8 Trailtalon 290 does and e not as restrictive as the Parkclaw 275 GTX.
It's very light and has decent responsiveness on the road & trail due to their minimalist nature. When they get water in them it drains out quickly and they didn't once feel too heavy on my feet.
They didn't grip amazingly on all terrains but they did pretty well and the sole is sure to last a long time before it becomes useless. In fact, it will probably get better and better the more worn out it gets because it'll be more flexible and less firm.
Compared to the Parkclaw 275 GTX from Inov-8 which were pretty great on any terrain they just cannot compete.
But if you’re looking for a lightweight, minimal trail shoe for the dry summer months then these are a good shout, though they won't be for everybody.

Vivobarefoot Primus Trail FG - Minimal shoe with big impact
Like many runners, I read about barefoot running and all the benefits it provides and decided to give it a try.
My first attempt was a cold December day in Utah in a grassy park, and I quickly lost feeling in my toes. Fail.
My next attempt was a warmer day on asphalt, but I kept getting rocks lodged in the bottom of my foot. Fail again.
Determined not to miss out on the barefoot running hype, I looked into a quality pair of minimalist trail running shoes. The Vivobarefoot Primus Trail FG is my first experience with a minimalist trail running shoe, and I have to say that I’m impressed.
I’m writing this review after logging 100+ miles over 5 months in the Vivobarefoot Primus Trail FG. These miles were accumulated over short trail runs and a number of hikes in the Rocky Mountains.
I also wear these shoes almost every day to work, in the gym, and on walks around the neighborhood.
Seriously, this might not be my go-to trail running shoe (I try to only do 1 minimalist run a week, max), but it’s my go-to shoe for everything else.
I’m a forefoot to a midfoot runner and lean towards zero to 4mm heel-to-toe drop for my trail running shoes, so this being a minimalist shoe with 0mm of drop fits perfectly in my preferences.
The weight comes in at a surprising 7oz, which I would never have guessed not looking at the specs. The shoe honestly makes me feel barefoot, and I hardly notice them on my feet. I would have thought they weighed less than 7oz, but the rubber outsole for foot protection is probably where most of the weight lies.
I love the look of the Primus Trail FG. Honestly, I like the look of all the Vivobarefoot shoes. I’ve gotten a lot of compliments on them at work and people asking what’s the brand/where can they find them.
It is great for work, hiking, or the gym. It really goes with any outfit (at least for the way I tend to dress). I’ve seen them in black and cordovan, and I think both colors look great.
The price is the biggest bummer for me. I got these shoes at a hefty $145. I don’t understand why a minimalist shoe with fewer materials would be so expensive, but it is what it is…kind of like how men's tank tops cost more than t-shirts.
Fortunately, I anticipate the shoe lasting a while, thereby validating the purchase, but it’s hard for me to fork over that much money for a shoe that likely won’t withstand the test of the Rocky Mountains more than a larger trail shoe.
Quality & Durability
For the minimal build of the shoe, I was expecting it to quickly deteriorate, but I’ve been pleasantly surprised.
The shoe has held up great with all the conditions I’ve thrown at it. Mud, water crossings, technical terrain, treadmills, asphalt, and more. No tears to the upper and the bottom are looking good, too. Some minor stitching has come undone on the upper, but it hasn’t affected fit or performance.
Cushioning & Sole
Cushioning is non-existent (the way it’s supposed to be for a minimalist shoe), so I haven’t really noticed any change in performance over time.
The rubber sole is great for gripping rocks and most trail terrain, but it doesn’t perform so well in wet conditions.
I’ve been slipping pretty badly on light snowfall in these shoes. So it’s definitely not a winter running shoe. You can notice the heavier wear on the middle-to-outside of the bottom, and this is due to slight supination I have.
The rest of the sole is holding up great and the small lugs still have great grip.
- Foot protection while still embracing the minimalist running concept
- High-quality and very durable
- Multi-functional shoe
- Looks great
- Very expensive
- Sizing is tricky
All in all, I really like the Vivobarefoot Primus Trail FG. It’s hard for me to recommend the purchase given the price, but I can honestly see myself grabbing another pair in 3-4 years to put back in the rotation.

I am pretty confident that this shoe is gonna last quite a while.
Properly functioning minimal shoe suitable for all surfaces except mud. A worthy evolution of VB’s trail offering. Long-term test shows very good durability.
Updates to Vivobarefoot Primus Trail FG
- The Vivobarefoot Primus Trail FG is a minimalist shoe that has the Firm Ground Outsole for maximum grip and enhanced resistance to abrasion.
- Its mesh upper is highly breathable in nature, which keeps the runner’s foot healthy and cool during the runs. Another interesting feature is the Quick Drain Zones which keep water from pooling in the foot-chamber. These zones also wick away moisture and perspiration.
Vivobarefoot Primus Trail FG size and fit
The footwear has the standard running length and the standard medium width of D and B for men and women, respectively. The footwear is most suitable for users with medium sized feet in terms of width. Also, its semi-curved shape enables the shoe to adapt itself to the shape of the foot and its changing movements.
The Firm Ground outsole is known for its excellent abrasion-resistant properties and enhanced grip on various terrains. The sticky rubber provides the needed traction while running and prevents slippage on wet or slanting surfaces.
Because the sole unit has an extremely low-profile construction, flexibility is easy to attain.
The Primus Trail FG doesn’t have a traditional midsole construction. The inner portion of the rubber outsole serves as the main underfoot platform. It’s designed to deliver an experience that is as close to the ground as possible. It caters to minimalist runners and people who have a neutral gait.
The Vivobarefoot Primus Trail FG features a breathable mesh material for a healthy inflow and outflow of air through the foot-chamber. The mesh assists in maintaining a properly ventilated environment inside the shoe. This mechanism keeps the user’s foot cool and dry throughout the running session.
The shoe houses the Quick Drain Zones which further improve the drainage system. These prominent pores prevent pooling when the runner is tackling wet surfaces and conditions.
For a seamless feel against the skin, the shoe utilizes the Fused Upper Material. The minimal construction enhances the experience of comfort for the user.
The Cable Lace and Toggle allows for quick and efficient lacing. Also, it effectively maintains the snug fit throughout the run, thereby preventing uncomfortable sliding of the foot inside the shoe while also providing a glove-like fit.
