Not recommended as a first purchase for beginners. The Primus Lite Knit is a barefoot training shoe with just a 3/4mm ultra-thin rubber outsole and a 1mm drop, offering almost no cushioning. The design relies entirely on the runner's own foot and calf strength to absorb impact. Beginners who run in it directly are highly prone to plantar fascia, Achilles tendon and calf injuries. If you do want to try barefoot running, start with walking: 15-20 minutes daily for 4-6 weeks to build foot strength, then attempt very short jogs (under 500m) and progress gradually. Never start with long or fast runs.
The Vivobarefoot Primus Lite Knit is a minimalist barefoot shoe with a 3mm ultra-thin rubber outsole that provides near-complete ground feedback and lets the feet work in the most natural way possible. Its remarkably thin 3/4mm stack with a 1mm drop, combined with an ultra-light 185g build, makes you almost forget you are wearing shoes. The knit upper is soft, close-fitting and highly breathable, making it suitable for everyday wear. The design philosophy is to make the foot muscles work actively rather than relying on cushioning and support, which means adaptation must be gradual. Start with short daily wear and progressively increase distance and time, giving the sole, calves and Achilles tendon enough time to strengthen. It is positioned for light exercise and commuting, and suits runners with barefoot training experience or those wanting to build foot strength. Beginners should not jump straight into long distances or high-intensity work with it, and it is entirely unsuitable for runners who need cushioning and support.
