One of the most impressive elements of this shoe is the outsole. It is able to provide a lightweight feel with maximum protection on the trails
. Vivobarefoot uses their patented soft ground sole in the designed o the Primus Trail SG. Out of all of their various outsole materials, this one is designed to hold up against the muddiest, rockiest, and toughest terrains. Since Vivobarefoot
is a line that prides itself on providing the most minimal ride on the market, the outsole design has the tough task of protecting the runner with a minimalist feel
. This outsole is made from a puncture proof material, Pro 5, which is actually 5 times more puncture proof than leading outsole rubbers. This material keeps the weight ultra light and the feel ultra minimalist without sacrificing protection and durability.
One of the unique things about this shoe is that it actually does not offer a midsole. Their less is more mantra really shines in their midsole design. Vivobarefoot
believes that all the extra midsole cushioning and layers of foam that goes into most runner shoe midsole’s hinder the natural development of the muscle in the feet and legs. They also ascribe to the belief that the added midsole foams keep the runner from feeling connected to nature and the ground below them. For these reasons, runners will not find a midsole in these shoes. This is a natural
running shoe that works hard to stay true to the natural movement of the runner's gait.
The upper is designed to repel water and keep the runner safe from potentially harmful debris that can infiltrate the shoe during trail runs
. Around the ankle, runners will notice a stretchy, adaptive collar. This provides a protective seal around the foot that keeps debris from entering the shoe. Although the upper is designed with various protective elements, it is still breathable and promotes airflow to the foot. The entire upper is made using a seamless design that reduces friction and lowers the risk of hot spots and blisters. It provides a second skin like fit that allows runners to forgo socks on their outdoor adventures. Finally, the upper is covered in a variety of quick-drying zones that wick moisture away from the foot and work to shake the excess water out of the foot after traversing through streams or puddles.
The upper of this shoe can do two difficult things that are often mutually exclusive. It protects the runner from water and debris and still allows for maximum airflow to reach the foot and circulate inside of the shoe. Runners reported that the breathability of this shoe helped keep them comfortable and reduced the risk of blisters
and hot spots, even on long runs.

Because of this, the shoe doesn’t have any added weight due to midsole cushioning or synthetic overlays on the upper. The outsole isn’t lined with heavy lugs or multiple layers of heavy duty rubber. This shoe is completed stripped and this keeps the weight extremely low.
Runners who like a minimalist or natural feeling shoe found this shoe to be very comfortable. The upper has a second skin feel that is caused by the fused, seamless upper design. Runners didn’t need to wear socks during their runs because the shoe works hard to wick away and drain away moisture. It also is made from a water-repellent material. All of these details translate to a very comfortable ride for the runner. However, if you are a runner who likes a cushioning, plush ride, this shoe will not feel comfortable to you because it lacks any additional cushioning. Read also about running sandals for men.
The Vivobarefoot Primus
Trail SG is not a shoe that is designed with a fashionista in mind. Instead, the focus of the shoe is on the development of a barefoot running powerhouse. Although the style and color that is offered are pleasing to many runners, the shoe only comes in one color options, so this is not the shoe that is for a runner who wants to see lots of color and styling options.
Runners will have a hard time finding a more responsive shoe than this one. This shoe provides the runner with superior ground support.

Vivobarefoot believes that the best running supports for the runner are their own natural gait and running pattern. They believe that by adding in unnatural supports, runners are actually hurting their ability to reach their full athletic potential.
The key protective element of this shoe can be found in the Pro 5 outsole material. This rubber is designed to be lightweight and puncture resistant.

Runners reported that this shoe could easily handle all types of off-road terrain regardless of how slippery, jagged, or steep.
This shoe is not designed for the runner on a budget. The Vivobarefoot line is a more high-end natural running line of shoes and will cost the runner more than the average shoe on today’s market. Additionally, runners reported that the shoe lasts an adequate amount of time, but isn’t anything outstanding regarding its durability.
The traction along the outsole of this shoe is unbeatable. Many runners commented on how safe they felt during their runs, even across the muddy and slippery terrain. The underfoot design is specifically created to grip the ground below without adding cumbersome weight or unnecessary technologies to slow the runner down.
This is one of the most flexible shoes on the market. Runners can literally twist the shoe, like wringing out a rag, while holding it in their hands. The ultra-flexible outsole and the lack of a midsole provide the runner with a shoe that supports the natural movement of the foot and the runner’s gait. There is nothing in this shoe to impede the natural movement of the runner and this shoe provides an almost second-skin feeling or the runner.
This is not a stability shoe at all. For the runner who is looking for added technologies to help with their over or under pronation issues. The purpose of this shoe is to provide the runner with a natural running experience and this means striping the shoe of any unnecessary technologies that will impede the natural movement of the runner’s gait.
Vivobarefoot brand shoes are known for their minimalist, zero drop format. Vivobarefoot engineers believe that the runner’s foot is the perfect technology and it doesn’t need additional cushioning in the heel or underfoot to change the gait cycle in any way.

For runners who are looking for a cushioning ride, this shoe is not the right choice for you.
