Product Info
FIRM GROUND OUTSOLE
Stand firm on multiple terrains.
3mmVivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.2.5mmTread 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 Firm Ground Outsole is made from a sticky rubber compound for maximum grip and durability. With a 3mm base and 2.5mm lug height, plus a textured arch for zonal grip (ideal for technical trail movement), this sole will keep your feet firmly planted on multiple terrains — wet to dry, concrete to rocky.Human beings aren’t separate to nature, we are nature. When we listen to it's rhythm and connect to its intelligence, we thrive. It's time to get outside and rewild.ORTHOLITE INSOLE
The Active Ortholite Performance Insole is made of 98% recycled PU foam, which helps reduce waste and the use of virgin plastics.
BREATHABLE MESH
Breathable, lightweight and comfortable.
PUNCTURE RESISTANT
The Pro5 Puncture Resistant finish is a lightweight and flexible 0.8mm layer on the sole. Protective underfoot to keep painful bits out, but still letting all the feeling in.
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.
