We recommend choosing half a size up from the size you think you need based on the size chart or your "usual" size in Xero footwear.
Please ensure you have measured your feet using our how to measure your feet guide.
These boots run a little small and do not suit wide feet. We would normally advise to allow 0.8-1.5cm leeway for boots, over and above your foot length, so check the size chart (which is a generic Xero chart) and choose the size that is half a size up from that.
