    I would have loved to make this shoe work, but with the fitting issues that I have, I definitely need something with more volume, and I also need a lot more flex...

  • The Vivobarefoot Primus Trail Swimrun is a running shoe that’s created for those who have neutral pronation. It makes use of a foot-shaped construction which allows the wearer to move freely. A sock-like collar design evokes a next-to-skin coverage that’s unrestricted. Moreover, a water-repellent mesh keeps the foot cool and dry throughout the running session.
  • A trail-optimized outsole offers traction and protection against impact. It’s thin, but it’s designed to resist punctures and abrasion. An orange hue makes the sole unit more visible during swim-run sessions. A 3mm removable insole adds a thin layer of cushioning for those who need it.

The Vivobarefoot Primus Trail Swimrun is true to size. It accommodates the general preferences of runners when it comes to length. The available width for the men’s version is D – Medium; for the women’s version, it’s B –Medium. It has a foot-shaped construction, which means that it mimics the natural curve of the human foot.

A sticky rubber compound is utilized for the outsole of this Vivobarefoot shoe. It delivers traction for the runner, ensuring surface control during the run. It has an orange color, which makes the shoe more visible when swimming.

Low-profile gripping lugs help in clamping onto various surfaces. These multidirectional nubs heighten grip on dry and wet paths.

The Pro 5 is an ultra-thin layer that protects the foot from punctures and other potential hazards. It’s advertised to be 5x more puncture-resistant than standard foam units that are as thick as this one. It doesn’t compromise the flexibility of the platform.

A 3 mm insole is used for the cushioning system of the Vivobarefoot Primus Trail Swimrun. It’s created using animal-free elements and methods. It can be removed or replaced with custom inserts.

A water-repellent mesh is used for the façade of the Vivobarefoot Primus Trail Swimrun. Its purpose is to deliver lightweight coverage in a breathable yet splash-resistant package. It is capable of staving off mild water infiltration.

The V-Web overlay system is heat-fused to the mesh upper. It aims to provide a durable structure to the shoe, as well as lightweight security to the foot. Moreover, it’s designed to stay intact, even when exposed to water.

Elastic laces are used for this product. They’re designed to complement a single-pull fit-adjustment system. They don’t need to be tied. A cord-pull fastener secures these strings while also maintaining the wearer’s desired tightness or looseness.
