[1] They were also worn by countrymen in Romania (opinca), Serbia, Croatia, Bosnia and Herzegovina (opanak), Bulgaria (opinka), and other countries.
A southern Albanian variety of opinga are the typical turned up leather shoes with red and black wool pompoms on the ends, which are often used for folk dances.
[3] The earliest archaeological evidence for opinga dates back to the 5-4th centuries BC, indicating they were an element in Illyrian culture.

[7] The artisans of the kaza of Përmet held the monopoly in the trade of opinga in the vilayets of Shkodër and Janina until 1841, when that privilege was revoked under the Tanzimat reforms.
