How to Choose the Right Size for Wide-Toe & Barefoot Shoes
Sizing barefoot and wide-toe shoes isn't quite like sizing regular ones — and getting it slightly wrong is the number-one reason people are disappointed with an otherwise great pair. The trick is that width matters as much as length, and a couple of minutes with a piece of paper will tell you more than any size chart. Here's a simple, reliable way to get it right.
Why barefoot sizing is different
Conventional shoes are often sized with a snug, tapered fit in mind. Barefoot and wide-toe shoes are the opposite: your toes need room to splay as you walk, so you're not just matching length — you're making sure the widest part of your foot fits the widest part of the shoe. A shoe that's the "right" length but too narrow defeats the whole purpose.
Step 1: Trace your feet
Do this at the end of the day, when your feet are at their largest, and while standing (weight-bearing spreads the foot to its true size).
- Stand on a sheet of paper against a wall, heel touching the wall.
- Trace closely around each foot, keeping the pen upright.
- Do both feet — most people have one slightly larger, and you size to the bigger one.
Step 2: Measure length and width
- Length: measure from the wall (heel) to the tip of your longest toe.
- Width: measure across the widest part of the foot (the ball).
Write down the larger foot's numbers in millimetres. These two figures are what you'll match against the maker's size chart — and because barefoot shoes live and die by width, don't skip the second one.
Step 3: Add a little length (toe room)
Your toes need space to move and to slide forward slightly as you push off. As a rule of thumb, leave roughly a thumb's width (about 10–12 mm) between your longest toe and the end of the shoe. Too tight and your toes can't splay; wildly too long and the shoe flops. Many makers already build this allowance into their charts, so follow the specific guidance for the pair you're buying.
Step 4: Check the shoe's own guidance
Sizing varies between makers and even between models, so always read the size notes on the product page. Some styles run large and are best ordered a size down; others fit true. Our product pages flag this where it matters — for example, some handmade leather shoes note "order one size smaller," while barefoot styles like the OmaKing Kuuda and wide-toe Kuutsid are cut roomy on purpose.
What if I'm between sizes?
For barefoot and wide-toe shoes, size up when you're between sizes — extra length gives your toes room to spread and is far more comfortable than a shoe that's a touch too short. With soft natural leather, a slightly generous fit also breaks in nicely and moulds to your foot over time.
Sizing kids' shoes
Children's feet grow fast and need room to develop, so leave a little more growing space — but not so much that the shoe slips at the heel. Soft, adjustable styles help; our KAKU kids' felt slippers use a Velcro strap so the fit can flex as little feet grow.
Frequently asked questions
How much toe room should barefoot shoes have? Around a thumb's width — roughly 10–12 mm — between your longest toe and the end of the shoe, so your toes can splay and slide forward as you walk.
Should I size up or down in barefoot shoes? If you're between sizes, size up. Extra length lets your toes spread and is more comfortable than a shoe that's slightly too short. Always check the specific model's notes, though, as some run large.
Why does width matter so much? Barefoot and wide-toe shoes are designed to let your toes spread. If the shoe is the right length but too narrow, your toes are still squeezed and you lose the main benefit.
When's the best time to measure my feet? At the end of the day, standing up, when your feet are at their largest. Measure both and size to the bigger foot.
