🖨️ How to Use the Templates

1

Print at 100%

Make sure your printer is set to "Actual Size" or "100% scale" – not "Fit to page"

2

Check the Scale

Verify the 5×5 cm control square on the template measures exactly 5 cm with a ruler

3

Step & Compare

Stand on the template with your heel against the line. Your longest toe should fit comfortably within the outline

💡 Pro Tip: Measure your feet in the evening when they're slightly larger. If you're between sizes, choose the larger one for comfort.

No Printer? Measure with a Ruler

If you can't print the templates, you can measure your foot length manually. Scroll down to the LENGTH section for detailed instructions.

LENGTH

The most important measurement for finding your perfect fit is the length of your foot. Here's how to measure it accurately:

How to Measure Your Foot Length

  1. Stand on a piece of paper with your heel against a wall
  2. Mark two points with a pencil: the tip of your longest toe (A) and the center of your heel (B)
  3. Measure the distance between these two points – from the wall (heel) to the tip of your longest toe
  4. Add an allowance of 10 mm to your measured length. The final length is the one you need inside the shoe

💡 Good to know: The leather will give a little with wear. Thanks to the anatomically shaped toebox, you don't need to add extra length, which would otherwise be necessary to achieve the required width.

WIDTH

LUKS Barefoot shoes are at their widest in the toebox and the middle part of the foot, but are narrow enough at the heel so they don't slip off.

They're a great choice for anyone who wants plenty of room for their toes to spread out, but without too much extra space at the front for comfortable walking.

We make our barefoot shoes in two widths:

Regular – for wide feet

Our standard width, suitable for most customers

Wide fit – for even more width

About 0.5 cm wider in the toebox and the front part of the shoe, while the heel remains almost the same width

Note: You'll find the exact measurements in the size chart for each model below.

We measure the width at the ball of the foot, specifically between the base of the big toe and the base of the little toe.

  1. Stand on a piece of paper with the outer side of your foot against a wall, so your heel is touching the wall
  2. With a pencil, mark the big toe joint (A) and the little toe joint (B)
  3. Using a ruler, measure the distance between these two points – from the big toe joint to the little toe joint

💡 Important: Do not add any extra allowance to the width measurement.

WHICH FOOT TYPES ARE LUKS BAREFOOT SHOES DESIGNED FOR

Slope foot type
Plateau foot type
Mountain foot type
Square foot type

✓ SLOPE & PLATEAU

Our shoes are unique on the market – anatomically designed to match the real foot shapes known as Slope and Plateau. If you have feet with a slope or plateau shape, you're in luck – our shoes are absolutely perfect for you and will fit like a glove.

⚠️ MOUNTAIN

If you have mountain-shaped feet, let us know that you need a more rounded toebox, and we will adjust any model from our range for mountain-shaped feet.

✗ SQUARE

Our shoes are not suitable for square-shaped feet, as your toes would not have enough space in our shoes.

🦶 VERY HIGH OR VERY LOW VOLUME FEET?

If you have a higher instep that require laces, Cordelia, Chelsea, Primavera, or Invierno have proven to be good choices.

On the other hand, slip-on styles like Fuego or Excellent are more suitable for low to medium instep. With a higher instep, they may feel tight and can be harder to put on.

For very low volume feet, these models may not be suitable and may need to be custom adjusted.
