The manufacture of espadrilles is generally more complex than that of sandals. The jute soles are the most critical part. The jute twines are first machine-braided. These braids are then manually formed into the shape of the sole and hydraulically pressed with heat to form the final shape and completed with vertical stitching. These basic soles are then vulcanized underneath. EVA foam or wooden heels are glued in place and more jute braids are wrapped around it to complete the soles. Uppers of different styles are then built on the jute soles to complete the espadrille.
