Vivobarefoot Primus Trail Flow 4.5

If you’re in to trail running, you’ll be well aware that keeping your footing is essential and some shoes can easily remove you from that sense of connection with the ground – whether through the soles being too chunky to the shoes not giving your feet and ankles the flexibility they need so you can respond to differing terrain and nuances in the ground you’re running over. We’ve covered Vivobarefoot products before and it’s fair to say they know what they’re about when it comes to designing footware for trail running. So, what’s with the Primus Trail Flow then?

First of all, the shoes are foot-shaped, not shoe-shaped. They have been designed to allow your toes freedom of movement and your feet the flexibility you would have if you were actually running barefoot. Secondly, the soles are thin (1.8mm base depth and 3.5mm lug height) meaning your feet get a real idea of the surface you’re running on and allow you to respond accordingly. The added benefit of this is that your muscles and tendons get a real work-out without artificial support that you see in more traditional running shoes and you’ll actually see an improvement in strength and flexibility over time. Thirdly, the material is extremely flexible and lightweight, cutting down on the weight you’re having to lift and adding to that sense of lightness while running.

The other thing Vivobarefoot focus on is sustainability and impact. The majority of the shoes are made from recycled materials and they believe the shoes are vegan (things like dye and adhesives are yet to be confirmed as wholly vegan), ticking another box of eco-friendliness. Oh and they also have a 100 day trial offer. After 100 days, if you’re not happy with them, you can get a full refund so go ahead, get running! RRP £150
