Sizing & Fit Guide
Find your ideal anatomical barefoot fit with ease. Natural foot health begins with zero constriction and room for proper, unhindered toe splay.
Metric centimeters (CM)
Independent sizing based on anatomical length.
Sizing Philosophy & Introduction
“Our shoes are sized based on the length of the foot. Since all companies use different methods to size their shoes, we highly suggest you measure your bare feet before ordering a pair.”
Centimeters Are Absolute
Shoe sizes (US, EU, UK) vary widely across international brands. Measuring foot length in metric centimeters provides an immutable, exact baseline.
Measure Later in the Day
Feet naturally swell and expand throughout the day. For the truest fit, measure your feet in the afternoon or evening after everyday activity.
Step 1: Measure Both Feet Accurately
Follow our 6-step physical wall-flush method. Most people have one foot slightly larger than the other; always size for the larger measurement.
Paper Placement
Take any piece of paper and place one edge flush against the wall.
Position Your Foot
Place your foot on top of the paper with your heel flush to the wall. Make sure paper doesn’t move.
Mark Longest Toe
Mark the position of your longest toe. It might be your big toe or your second toe.
Repeat on Other Foot
Repeat steps 2 and 3 with your other foot.
Measure with Ruler
Use a ruler and measure from the edge of the paper to the mark you made.
Order for Largest Foot
Choose the largest measurement of the two when ordering.
Keep Pencil Perpendicular
Angle your pencil straight at a 90° vertical angle when tracing the toe marker. Slanting inward or outward will add or subtract length, shifting your barefoot shoe size.
Step 2: Compare to Chart
Evaluate your recorded measurement against our foot length brackets.
Shoe Dimensions
“Here you will find the width of our shoes. For now we only have ‘regular’ width. We will have wide sizes available in the future.”
