Vivobarefoot Motus Flex Natural 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.
