Sizing
Our shoes are unisex and fit true to size, although they may feel spacious if you've not worn barefoot shoes before.
If you're between sizes, we recommend sizing down.
For greater certainty, choose the internal length that best fits your foot. Simply trace around your foot with a pencil and paper and measure the longest distance from heel to toe. An internal length 5-12mm longer than this measurement should be about perfect.
