The Primus Lite 3.5 is our original training all-rounder, reimagined with a new upper to get us closer to circularity. Made for moving naturally and building natural strength during runs and wide-ranging training disciplines, it’s perfect for experienced barefoot cross-trainers and those new to barefoot performance.
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.
