  • The Vivobarefoot Primus Lux is a road shoe that’s designed for the neutral pronator. It has a lightweight and flexible construction that mimics a near-barefoot style of performance. The upper unit is made of tanned animal leather, a material that is durable yet flexible.
  • Underfoot support is provided by a thin thermoplastic polyurethane unit. This full-length aspect of the shoe also serves as the outsole. A puncture-resistant layer shields the foot from abrasion and harmful elements on the surfaces.

This Vivobarefoot shoe for running was crafted to be true to size, though it would be helpful for runners to try on the shoe first before deciding on a purchase. When it comes to width, the available options are D – Medium and B – Medium for men and women, respectively.

The outsole unit of the Vivobarefoot Primus Lux features ground-contact TPU (thermoplastic polyurethane). This compound is meant to provide traction and a flexible underfoot experience.

The PRO5™ technology is a very thin layer that is resistant to punctures. Its job is to protect the foot from the abrasive nature of the elements on the paths.

A hexagonal tread pattern is tasked with heightening surface grip and flexibility.

The TPU sole is responsible for carrying the foot throughout the running session. It has been configured to resist sagging or early material breakdown. The thinness of the construction permits the wearer to get a feel of the ground beneath.

A leather footbed is placed on top of the main platform. This add-on offers a bit more cushioning without sacrificing flexibility. It also follows the contours of the underfoot, thereby supporting sections that are not usually given attention.

The upper unit is made of Pittards® animal leather. The material is not thick, yet it has been constructed to be durable and flexible. It has tiny breathing holes to maintain a cool and dry interior for the foot.

The elements on the upper are stitched together, not glued. Such a configuration heightens the overall sturdiness of the façade.

Round laces go through stitch-reinforced eyelets on the instep. These fabric cords are designed to adjust the tightness or looseness of the fit while also preventing in-shoe wobbling.

The heel lining is made of leather. Its goal is to keep the back of the foot in place and prevent it from exiting the foot-chamber unintentionally.
