5️⃣ Preparing the Rubber Sole – A primer is applied to the sole to ensure perfect adhesion before applying the glue.
6️⃣ Applying Polyurethane Glue – The glue is carefully applied with precision, using a brush or even a toothbrush.
7️⃣ Gluing the Upper & Glue Reactivation – The upper is also glued and heated in the flash oven for an optimal bond with the sole.
8️⃣ Final Assembly in the Press – The two parts are manually aligned, then placed in a 6-bar press to ensure a perfect fixation.
9️⃣ Finishing Touches & Adjustments – Once removed from the mold, our artisans apply precision glue using a syringe to fill any small gaps between the fabric and the sole. The glue is then reactivated with a hairdryer, and both parts are hand-pressed for an impeccable finish and maximum durability.
🔟 Cleaning & Quality Control – Each pair is inspected, cleaned, and carefully checked to remove any glue residue and ensure a flawless final product.
Through this detailed artisanal process, Espigas guarantees exceptional quality, combining comfort, durability, and authentic craftsmanship.
