Good to know

- Barefoot-like running is the name of the game when it comes to the Vivobarefoot brand. The products that are released by this name are designed to deliver natural performance that is protective and secure. An example of such a creation is the Primus Knit, a daily driver for style and the pursuit of an active lifestyle.

- The facade of the Vivobarefoot Primus Knit is similar to sneakers, with a leather-reinforced mesh upper and a one-piece construction forming a look that is visually reminiscent of fashion-optimized footwear. A combination of an environment-friendly insole and a thin outsole handles cushioning and natural stepping motion.

Vivobarefoot running shoes are sized bigger than the standard, according to their website. However, runners are advised to still purchase their usual size preference because the shoe is intended to fit with a gap between the toes and the tip of the shoe.

The overall sideways fit is influenced by the foot-shaped curve of the whole product, the roomy configuration of the toe box, and the form-fitting fabrics of the upper unit.

The outsole unit of the Vivobarefoot Primus Knit is made of rubber. This full-length piece fundamentally serves as the actual platform, receiving the shape of the foot and supporting it like traditional midsole units. It has a 3-millimeter height to separate the foot from the ground beneath. Proprioception, or ground-feel, is encouraged by close-to-the-ground shoes. Another example of a series that has thin sole units is the Merrell Trail Glove.

Above the rubber sole unit is a Bloom™ Performance Insole, which is an add-on that is derived from algae. Such a design is environment-friendly. The insole itself offers some semblance of cushioning. It can be removed or replaced with a new one if the wearer wants to do so.

The upper unit of the Vivobarefoot Primus Knit is primarily made of a knitted fabric. This material has a flexible and form-fitting construction to permit the natural shape of the foot as it goes through the gait cycle. Small holes allow air to enter the foot chamber and maintain a ventilated running session.

Leather panels are stitched onto the back, the sides and the front. These elements are meant to reinforce the structural integrity of the upper unit and help in the attainment of a secure fit.

A one-piece opening permits the foot to experience a sock-like fit. The connected collar and instep evoke the shape and texture of a sock’s topmost portion, even having a stretchy and seamless material to further sell the design.

Flat shoelaces snake through discreet eyelets on the tips of the leather panels. These accouterments work together to deliver a customized in-shoe experience, tightening or loosening the in-shoe hug to suit the preference of the wearer.
