Millions of years of evolution have done an amazing job. The human foot is perfectly designed for standing, walking, and running.
Remarkably, feet come in all sorts of shapes and sizes. Some have been compromised by a lifetime in conventional shoes, some naturally wider and some thinner and longer. We’re confident you’ll find a pair of Vivos to suit you.
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.
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.
This is the shape of the recommended fit of Vivos. Remember, it might not be your preferred fit.
If you prefer a roomier fit or think you have wider-than-average feet, you might consider going a size up.
The Primus Flow is the newest member of the Primus family, designed for pinnacle barefoot running performance. Built for efficient and unrestricted natural movement, this ultra-lightweight runner – our lightest ever – weighs in at just 150g. Its lightweight, breathable upper made from engineered recycled mesh forgoes overlays in favour of a stripped-back, seamless construction.

*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.

Once you can’t repair or don't need them anymore, send us your old Vivos and we’ll make they sure they’re given a second life, or if they’re really well-loved, we'll store them until we launch our recycling solution.
For natural stability, natural sensory feedback and natural strength.
