The Primus Trail II Firm Ground is the original and best-selling trail running sneaker by Vivobarefoot. Lightweight, durable and flexible, it's perfect for varied trail adventures, bringing you closer to nature.
Sizing
Vivobarefoot's shoes fit 'big' deliberately. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you've more than likely found your ideal size. Don't forget to check out the size guide, which in this case, indicates the length of your foot, not the inner length of the shoe.
Primarily a trail shoe, the Primus Trail II FG also excels for fastpacking and hiking. A popular choice for HIIT sessions and strength training. Its width and flexibility provide supreme sensitivity and natural mobility on uneven terrain. The quick lacing system allows for easy donning and adjustments. The Firm Ground sole balances sensitivity, grip and speed on various hard terrains, naturally building strength with every step. Made in Vietnam. Continuously improved through athlete testing and material innovation, the Primus Trail II FG delivers exactly what you need: performance materials, recycled and vegan*.
*The main materials in all Vegan products from Vivobarefoot are synthetic and not derived from animals. However, Vivo currently lacks full transparency regarding the production of some small components (such as adhesives and dyes) used in these shoes. While they believe the shoes are vegan, they cannot yet guarantee this and aim to be fully transparent about it.
