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.

HOW TO MEASURE
Make sure you measure your feet standing up, not sitting down, and we recommend you do this later in the day, as feet tend to expand from when we first wake up.
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.

FITTING
Measuring your feet will help tell us what your recommended fit is. However, some like a shorter, snug fit while others prefer a longer, more spacious fit. This is where personal choice comes in.
It’s also important to note there will be slight variations in size from one style to another. Please check the product page to check if a style runs large, small or true to size.
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.
Collar and Tongue Lining (60% RPET, 40% Polyeurathene Microfibre)
Laces
100% RPET
outsole

Care
Cleaning
Brush off mud and clean with a damp cloth
Drying
Remove insole and dry at room tempreture. Keep out of direct sunlight and avoid putting on a radiator.
Aftercare
LIQUIPROOF PREMIUM PROTECTOR. With wear, your shoes may loose some water resistent quality that is applied to the textile of the shoes. This product can be used to replenish the water repellent qualities.
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.

Built for barefoot training, inside and out
The Primus Lite All Weather is for barefoot warriors who train in the wild. An all-weather, water-resistant version of the original Primus trainer, designed to help you build strength in every run, walk or workout — come sunshine, wind, ice or rain.
Fit, Feel, Flex
For natural stability, natural sensory feedback and natural strength.
PRIMUS OUTSOLE
The Primus Outsole is a light and thin 2mm performance outsole that's designed to put as little as possible between your feet and the ground. The side wall profile is as low as it can be, giving it a slightly lower profile towards the heel, and the sole subtly overlaps the toe — offering enough protection for urban environments, without compromising natural movement. Strong geometric shapes lead to strong feet, so the tread pattern uses our signature hexagonal design to help multidirectional flexibility and grip.
