Our Huaraches sizes follow the US measurements of Shoes, our huaraches are very true to size and commonly fit well according to the US Sizes. Since feet are always different there could be the chance that you need a different size than what you normally wear in shoes. We have created below chart that helps to identify what is your best size to wear our amazing Artisan Made Huaraches.If you are a half size in your shoes, we commonly see that going up has shown the best results. i.e. If you a size 6 1/2", our size 7" shows to be a very good fit.
