Good to know

  • The Vivobarefoot Primus Trio II is the improved revival of the original version of this minimalist training footwear. Its name is based on the trio of materials used, which are leather, suede, and mesh for a unique experience during everyday workouts. While its predecessor had a version for each gender, the current trainer is now specially designed for women. This update has a cleaner and sleeker look to it than the previous one. Meanwhile, the signature features are still retained, such as the wild hide leather footbed, mesh upper, and TPU sole.
  • However, the suede received a makeover. According to the brand’s claims, the 2.2 mm thick material has now been sourced from the healthiest animals for a distinct feel, quality, and shape.

The Vivobarefoot Primus Trio II is engineered to accommodate the biomechanics and foot dimensions of the ladies. It comes in an extensive range of US sizes, from 5.5 to 11.5. It is reported to run big concerning length. The brand has advised that it is normal to have a thumb width of space from the toes to the toebox.

The PRO5 technology lends a close-to-the-ground feel to the Vivobarefoot Primus Trio II. It is a patented layer that has lightweight, ultra-thin, and puncture-resistant characteristics. It is five times more resistant to penetration compared with the standard outsole of the same thickness. Made of a durable TPU compound, it is meant to enhance the underfoot proprioception of the wearer.

Since the Vivobarefoot Primus Trio II is a minimalist trainer, it doesn’t have a dedicated midsole. Instead, a tier of leather footbed sits atop the outsole. It gives a cozy experience to the sole, which helps the wearer focus more on their workout.

The Vivobarefoot Primus Trio II is composed of a lightweight mesh fabric, created from synthetic multi-ply materials. It offers breathability and comfort.

2.2 mm thick leather suede overlays reinforce the key areas, such as the heel, medial, and toe sections, to prevent rips and improve support. They are sourced from large and healthy animals for improved quality of the material.

A traditional lace-up closure grants secure foot lockdown. It also boosts lateral support since it makes the sides more rigid as the shoelaces are pulled taut.
