Our Clog sizes are general and are based on men's US sizes. The clogs are whole sizes so the best fit for someone who wears a half size will be the size up (ex. size 7.5 should order size 8/9). Our sizes are based on measurements and do not match up exactly with the size imprints available at our factory for size 10/11 and above. Please refer to the chart above to match the correct size by measurement to the shoe imprint. Use "Our Clog Size" when ordering.
