Soft Ground Sticky Rubber Outsole

Sticky Rubber outsole with aggressive lug design, customised to avoid clogging, with tooth like side lugs for traction. Made for soft, wet and muddy surfaces. Not suitable for the city... or the faint hearted.


Produced using animal free products and processes.



Amazing product! Very comfortable and durable! Great for all terrain, hiking in the woods in British Columbia, walking the malls and city streets in Vancouver. Only thing is the don't have much grip in wet conditions, very slippery on wet logs, rocks and icy surfaces.

Love the fit and comfort, love the durability and fashion!


I love the design of these shoes. I use them for water sports so the sticky orange sole is perfect.

The one flaw I will mention that is frustrating is the tab at the back of the shoe, the change of material seems to cause a bit of friction on the back of the foot, which means I have to wear socks...

Otherwise one of my favourite pair of Vivo's!

Probably my best ever investment

I'm a long-time fan of barefoot products but these Primus Swimrun shoes are awesome.
They are comfortable, a great fit and perform exactly as advertised. I haven't had them long so I can't comment on how durable they are, but based on my initial experience I can't recommend them highly enough. Top marks, Vivo!
