Vivobarefoot Primus Trail III All Weather FG Mens Barefoot Shoes

Size Guide
Size Guide - Vivobarefoot

Place a piece of paper larger than your foot against the wall. Ensure that the wall is flat, and if there is any skirting, it is also flat. 

Stand on the paper with your heel against the wall. Ensure that the floor is hard and that the paper does not slide under any gap between the floor and the wall/skirting.

Mark the paper where your longest toe reaches with the pencil. Remember to not tuck the pencil under the toe as you want an accurate maximum measurement.

Measure the distance from the end of the paper to the toe line with a ruler or tape measure.

Repeat with your other foot, they might be different – trust us on this one! – and then use the longest measurement.

Use our conversion tables below to work out your recommended fit.

RECOMMENDED

SNUG

 

This shows how a shoe would fit snug. It’s still a correct fit, but with less space around and at the front of the toebox. 

RECOMMENDED

 

This is the shape of the recommended fit of Vivos. Remember, it might not be your preferred fit.

SPACIOUS

 

If you prefer a roomier fit or think you have wider-than-average feet, you might consider going a size up.

ORTHOLITE INSOLE

The Active Ortholite Performance Insole is made of 98% recycled PU foam, which helps reduce waste and the use of virgin plastics.

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.

Run wild, whatever the elements

All-weather sneakers for speedy hardpack trail adventures 

A true barefoot trail runner for cooler, wetter conditions, the Primus Trail III AW FG also excels at fast hiking, fastpacking and other speedy, hardpack trail adventures. It’s also popular for rainy, outdoor-forward city living.

 

It’s wide, thin and flexible for full feeling and natural mobility on uneven ground. The quick-lace system allows for fast on-off and easy adjustments. And the Firm Ground sole balances sensitivity, grip and speed on varied hardpack terrain, building natural strength with every step.

Multi Terrain

Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
