Primus Lite II BIO Mens


Primus Lite II Bio harnesses the power of plants to deliver a high performance shoe that puts you in touch with the ground under your feet in the best possible way, benefiting your feet and the planet.

We're confident that after experiencing the joys of natural foot freedom, your feet won't want to go back to 'normal' shoes.

So confident, we've introduced a 100 day trial to all orders. If you change your mind within that period, we're happy for you to return your shoes for a full refund with no hassle.

Your trial will commence automatically from the date your order arrives. Simply check out with your shoes as usual and we'll take care of the rest. (Standard Ts and Cs apply).



Primus Lite II Bio uses a natural by-product of the field corn food industry, Susterra® Propanediol; petroleum free, non-toxic and 100% USDA certified. Developed by DuPont Tate & Lyle Bio Products, its allowed us to create a high performing shoe that is our lightest and most environmentally sound yet. Add a mesh made from Sorona® plant based fibres and you have what we think is the least petroleum reliant performance shoe in the world.

Love em

I have a pair of Magna trails for those adventurous days but these are great for casual wear and working out indoors. Comfortable and breathes very well. Only issue is the insert and wearing them barefoot is uncomfortable at first but from breaking them in it's great. Plenty of room for my wide foot and has great traction. Color will put some people off but I love the design and color. Naturally I wear a 10 but with vivo shoes I wear a size down and it fits great. Had a pair in size 10 and it was too big. Great shoe overall.

Beautiful shoes, first size tried was too big

The shoes are beautiful and move well with the feet. I love how featherweight and flexible they are, not to mention what they’re made of! One issue: I typically wear a men’s 9 US and a 42-43 EU. Thus I received a size 42. It appears to be a size too large, with a bit more than a thumbs width extra length. We shall see how a 41 fits!
