The menorcan sandals known as Avarcas (or abarcas) is a type of sandal popular in the Balearic Islands (Spain), especially in Menorca. They are also popularly known as "menorquinas". Avarcas are made using natural leather for cutting and insole, and a synthetic sole, generalemten of rubber or polyurethane.
The avarca is a traditional sandal originally developed in Menorca, in the Balearic Islands. The original avarcas were made with leather for the top (the cut), while the floor was a piece of recycled car tire. Nowadays the soles of the avarcas maintain the original design with a drawing in the floor similar to the one of the tires, but made with a mold for such purpose, like any other synthetic foot of modern footwear. This way the soles are sturdier and much lighter than the original car tire.
In short the avarca is a fresh, very comfortable, light and resistant footwear.
Although the originals began to be made on the island of Menorca, there are manufacturers of other localities, such as Elche, which currently manufacture avarcas of the highest quality.
