About Vivobarefoot -
Vivobarefoot was founded with the intent of creating a range of footwear that is made to accommodate our feet - not the other way around. Vivo focus on creating products that move with our feet, connecting us with nature, and allowing us to reach our full physical potential.
All Vivobarefoot shoes have a wide, flexible, thin design, making each shoe the closest to barefoot we can be! This design promotes your foot’s natural movement patterns, strength, and allows each wearer to feel more grounded and connected with the natural world that we are increasingly removed from. Not only do Vivobarefoot want the best for our feet, but they are a B Corporation(™) Certified business for good, making them a company that uses their business to build a more inclusive and sustainable economy. Each shoe is made with natural, biosynthetic and recycled materials, and has a sleek, sophisticated appearance that we love.
