Not Sure of Your Size? Start Here
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
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
I love these socks. Just need them in lots of different colours / patterns next ❤️
The most comfortable socks ever, if you fancy a day off from your toe socks or just fancy less hobbit-like looking feet - these are a game changer!
They are fantastic!
