Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.
If you need any advice about sizing, please feel free to drop us a line at: service@sunnoss.com
The measurements in the description of individual products are taken only across the front side of the garment, not around the circumference (e.g. chest and waist).

Run and roam wild
Built for trail running and adventuring closer to nature
The Primus Trail 3.5 FG is for runners who live for the end of the road. These all-terrain trainers are light and flexible enough to move freely, and tough enough to run wild on rough, rocky ground. Made with recycled, vegan*, high-performance materials.
We're on a mission to create a fully circular shoe – a new Vivo made from an old one, which can in turn be made into another. The Primus 3.5 is a big step forward on this journey.
With an already mechanically recyclable outsole, the challenge is making an upper from 100% polyester, which can be recycled. The new Primus Trail 3.5 upper takes us from 34% to 76% polyester, of which 93% is recycled. Why not 100%? Because some parts of the upper still need extra durability that polyester can't yet provide. We’re working with our partners to figure out this final piece of the puzzle.
Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.

Whilst we recommend 6-14mm, the amount of space you have will depend on how the length of your feet compares to the sizing
The ideal fit for you will depend on how wide your feet are and/or if you prefer your footwear to fit snug or spacious.
NARROW FEET/SNUG FIT:
Vivobarefoot's research suggests that if you measure to the top end of the 6-14mm suggested toe allowance; for example, if you have 12mm but have narrow feet and/or prefer a more snug fit, you may prefer a size down. They suggest at least 4mm toe allowance, even for the narrowest feet.
WIDE FEET/LOOSE FIT:
If you have wide feet and or prefer a spacious ‘roomier’ fit, you may prefer to have more than 14mm space at the front.
Caution: Risk of trips and falls is increased with additional length therefore we advise caution when transitioning into wearing your preferred size footwear if it is larger than you’re used to. Many Vivobarefoot customers have very wide feet and enjoy 20mm toe space without any issue, we simply advise caution if you are new to wearing a more natural fit.
