The Mexican sandals are 100% genuine leather, handmade very comfortable slip on we recomend that if you are a half size like a 7.5 you go down half a size to a 7. The leather on the sandals stretch after a few uses, they mold onto your foot. Each pair is handmade 100% authentic leather ( Note: FOR WOMEN'S SANDALS you will receive shoes marked with the Mexican size for Example when you order a US size 7- you will receive shoes marked with a "4" which stands for Mexican size 24.)
