The Vivobarefoot Primus Trail FG II is the specific trail running shoe from the British minimal shoe pioneers. It is built on the basis of the Vivobarefoot philosophy ofbeingwide, thin and flexible and as close to barefoot as possible.

The shoes appear very durable so far, after multiple hours running on trails, including plenty of muddy river banks and woods with fallen logs. There are a few creases, but all the materials are bonded well, and they seem to be decently put together. The upper mesh is super flexible, and Vivo appear to have put some extra stitching where the mesh meets the more substantial side plastic in this area. Time will tell, but our money would be on this area failing first.

Most reviewers of the Primus Trail II All Weather FG say that the shoes offer great durability and comfort during the colder weather, though, along with improved foot protection. This is compared to the Primus Trail II FG, which is more suitable for less intense weather.Again because of this tougher plastic upper, there is reduced breathability. And with these shoes being designed in England, it’s not such an issue there, but if you’re in the heat of Texas, take that in to count. If the material is an issue for you, there is a knit option that you may want to try instead, which will be more forgiving and possibly reduce any sore spots.

Another option is the Primus Trail Knit FG , which has seamless construction and a knitted upper that promotes flexibility. Fit and Sizing The Primus Trail II FG shoes are an upgrade from the first Primus Trail FG footwear . That said, there are only minimal differences, with reviewers stating that the Primus Trail II FG is more durable than its predecessor. Furthermore, the newer version has a slightly wider toe box and a better foot-shaped design to encourage more natural stability and movement.

Overall, the Vivobarefoot Primus Trail II FG is a pretty good trail-focused barefoot shoe, but there are a few cons worth mentioning about this model. The first thing to like about the Primus Trail II FG is that it provides adequate foot protection on different types of trails. The “FG” in the name of this model stands for “Firm Ground” which is a means of classifying particular soles used in some Vivobarefoot Shoes. The FG in this model basically adds to this shoe’s protection and gives you a slightly more stiff sole to walk on. The Addis are made in Ethiopia, while the RA are made in Portugal. The RA feel better constructed, but are more expensive as well. Though I prefer the Addis because they are slightly wider, more stable in a way. I have both the regular version and the Oxford. Fantastic shoes.
