Why Foot Shape Matters
Not all feet are shaped the same, and neither are barefoot shoes. Understanding your foot shape helps you find shoes that fit naturally without cramping your toes or leaving excess space.
Unlike conventional shoes that force feet into a standardized shape, barefoot shoes are designed to match natural foot contours. But each brand interprets "foot-shaped" differently, which is why knowing your foot type is essential.
The Four Foot Shapes
Slope (Egyptian)
The most common foot shape. Your big toe is the longest, with each toe progressively shorter, creating a diagonal slope.
Characteristics: - Big toe is longest - Toes slope down smoothly - Often has a narrower forefoot
Best brands: Most barefoot shoes work well, but tapered toe boxes from Vivobarefoot and Xero Shoes often fit best.
Mountain (Greek)
Your second toe is longer than your big toe, creating a peak or "mountain" shape.
Characteristics: - Second toe is longest - Creates a triangular silhouette - May need extra length in shoes
Best brands: Look for shoes with a peaked or pointed toe box. Vivobarefoot Primus line, Xero Shoes, and some Merrell models accommodate this shape well.
Tip: Size up if your second toe feels cramped. The extra length matters more than overall foot length.
Plateau
Your first two or three toes are roughly the same length, creating a flat "plateau" across the front.
Characteristics: - Multiple toes of equal length - Wider forefoot - Needs a roomier toe box
Best brands: Altra and Lems have boxy toe boxes that accommodate plateau feet well. Their "FootShape" designs give equal room to all toes.
Square
All toes are approximately the same length, creating a squared-off front.
Characteristics: - Toes form a straight line - Widest forefoot of all types - Needs maximum toe box width
Best brands: Altra and Lems are your best friends. Their extra-wide toe boxes are designed for this foot shape. Avoid tapered designs.
How to Determine Your Foot Shape
The Wet Foot Test
- Wet the bottom of your foot
- Step on a piece of dark paper or cardboard
- Step off and examine the print
- Look at the toe area to see your shape
The Trace Method
- Stand on a piece of paper
- Have someone trace around your foot while you're standing (weight distributed)
- Examine the toe outline
Understanding Volume
Volume refers to the height of your foot—specifically your instep (the top of your foot).
Low Volume
- Flat feet or low arches
- Low instep
- Shoes may feel loose on top
- Look for shoes with adjustable closures
Medium Volume
- Average arch height
- Most shoes fit well
- Standard barefoot shoes work
High Volume
- High arches
- Pronounced instep
- May need shoes with stretchy uppers or extra depth
- Boots and high-tops often fit better

Tips for Finding Your Perfect Fit
- Measure at the end of the day - Feet swell throughout the day
- Measure both feet - Most people have slightly different sized feet
- Allow 1-1.2cm of space - Your toes should not touch the front
- Check width, not just length - A shoe can be the right length but too narrow
- Consider volume - High insteps need different shoes than flat feet
