Already from the days of the first colonists that arrived on the island towards the 9th century BC, fishing constitutes one of the mainstays of the economy. The above opanke-style shoe is called "skinskor" and is made in one piece of salmon-skin. The raw skin is soaked in urine for two to three weeks and then rinsed in water and sun-dried. The shape is cut in size around the foot and a slit is made only on the toe and heel-part. The slit sides are hand-sewn together with sinew. The sole-part is always cut from the salmon’s back, whereby the scales are left on the skin for better traction on the wooden decks of ships. The insole is made of a handful raw sheep’s wool. For home-wear these shoes were also made of sheepskin, while the insole was then made of knitted wool with colourful geometric designs.
