Barefoot shoe sizing works differently from standard high-street brands. Measuring your feet in centimetres is the essential first step to getting the right fit.
The Wall & Paper Method
A simple 5-step process you can do at home with just a piece of paper, a pencil, and a ruler.
Room to Move
Adults need 0.8–1.2cm of space; kids need 0.8–1.5cm of growing room beyond their foot length.
Width Matters
Barefoot shoes have wide toe boxes, but width fitting is just as important as length for comfort.
Customer Reviews
Very comfortable, I wasn't sure I would like the feeling of them but I don't notice them on and love the fact that they are not too tight around the top either.
Excellent customer service, swift dispatch and delivery, highly recommended, will definitely buy from them again. Thank you.
Lovely socks and brilliant customer service. Thank you!
Fast delivery
My daughter loves them
Perfect
Super comfortable, I have sensory issues and socks have long been a struggle - I plan to switch over to these completely
Lovely socks… I’m now a total convert to toe socks, they are so comfortable! These are great for summer in trainers, breathable and just the right height. I’m about to buy more.
Helpful friendly and easy
Great socks, comfortable and not restrictive on the toes.
So comfortable,I need more!
Great customer service and so friendly. If you have a problem they are quick to sort it out with ease. Amazing people. Love you all. Thanks for bringing this shop to life. Dan is amazing.
They are great quality and so comfy. My daughter HATES mainstream socks because of the bar across the toe section but absolutely LOVES these. Thank you so much.
Great socks, very comfy. Just need more variety instead of basic black or white
Easy to use. Delivery was good too
