The Syncrasy uses industry standard US sizing with a unisex mold. The majority of our users find the Idio Syncrasy's to fit in the same size as their athletic shoes. Historically, exchanges are typically requested for half a size up based on individual preference. This size chart provides the heel-to-toe measurement that can often be compared with your current manufacturers' size guide to help determine the best fit for you. Please reach out to discgolf@idiosports.com with any sizing inquires.

If you have not sized your foot in some time, we suggest visiting a sporting goods or footwear store to have your foot professionally measured. This chart below should be used if that is not an option. For best accuracy, be sure to measure more than once preferably with the help of a friend. Should you have any questions about sizing or the fit of the Syncrasy, please reach out to discgolf@idiosports.com
