"Modern shoes are the foot’s first enemy."
—William Rossi
If you’ve been on the hunt for barefoot shoes that improve your foot health while being versatile enough for everyday wear, you’ve likely come across Vivobarefoot. As someone who’s always looking for ways to boost performance, reduce injury risk, and keep my body aligned with its natural movement, I’ve been testing out a few models of Vivobarefoot shoes lately: the Primus Lite 3.5, Primus Lite IV All Weather, and Motus Flex. I bought them at one time so that I could compare and contrast and I’m glad I did. Each of these shoes brings something unique to the table.
Let’s break them down.
What Makes Vivobarefoot Different?
Before jumping into the comparisons, it’s worth mentioning what sets Vivobarefoot apart from other footwear brands. Their focus on natural movement and foot health is at the core of their design. These shoes are engineered to support the natural biomechanics of your feet, which means you’re going to feel more grounded and mobile, no matter the activity. The lightweight, flexible design allows your feet to move as they would if you were barefoot, which is key for improving balance, strength, and performance.
