Product information
Primus Outsole
Get as close to the ground as possible.
Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.
2mm
Tread depth refers to the thickness of the patterns or “lugs,” on the sole. These are purposefully designed to cater to specific surfaces and conditions, providing an ideal combination of traction, grip, and a sense of connection with the ground.
The Primus Outsole is a lightweight 2mm performance sole designed to keep you close to the ground. A low sidewall and subtle toe wrap offer just enough protection for urban environments without limiting natural movement. Its hexagonal tread pattern supports multidirectional flexibility and grip – because strong shapes build strong feet.
Reclaim your natural potential
Shoes that put fashion before fitness and money before wellness? The unnatural isn’t working. It’s time to get back to basics and let nature heal us.
Ortholite Insole
The Ortholite Performance Insole is made of 98% recycled polyurethane foam, which helps reduce waste and the use of virgin plastics.
Breathable Mesh
Breathable, lightweight and comfortable.
VEGAN*
*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
