Costa, sandal with tubular straps that hold the foot and cross over the instep. It has a square toe and a thick moon-shaped heel, all made of soft suede leather. The leather used in Cortana shoes undergoes a tanning process that ensures that the water used is completely purified before being returned to the environment. The sole is made of greased leather and hand-painted in the same tone as the leather. Any small defects that may appear attest to the craftsmanship, giving each pair a unique value. Heel height: 7 cm
