Panama's indigenous Guna community are demanding US sports giant Nike withdraw its latest shoe over its "pirating" of a protected traditional design.
Lawyers for the Guna say the special-edition Air Force 1 model shoe sports a traditional "mola" design without their permission, flouting their intellectual property rights.
They want the company to pull out of a planned June 6 launch of the $100 shoe.
Industry website Sneaker News reported that Nike says the design is a tribute to Puerto Rico and features a graphic representing the native Coqui frog.
However, Guna chief Belisario Lopez told a press conference in Panama City: "They must recognize that the mola that appears on the Nike shoes is from the Guna people."
Lopez said the Guna people's case against Nike "is not the only one in the world. Thousands of designs and the ancestral knowledge of indigenous people are being pirated by multinational companies."
Guna lawyer Aresio Valiente told AFP the indigenous people were seeking damages and the withdrawal of the shoe, "which is part of the spirituality of the Guna people".
"So the company has to compensate us because it was an illegal copy of our designs," Valiente said.
"We have already sent a note of protest to the Nike company, but we have not had an answer."
The Guna people live in communities in Panama and Colombia. Most Guna live in Kuna Yala, also known as the San Blas islands, off the Caribbean coast of Panama. Environmentalists say the low-lying islands are being threatened by rising seas due to global warming.
"The mola is like a flag for the Guna. There is really a cultural identity that is articulated around the mola. It is a very strong element of identity," said Monica Martinez, professor of social anthropology at Barcelona University who has been studying the Guna for nearly two decades.
There are "more and more cases" worldwide in which indigenous people are reporting theft of their intellectual property by designers or large companies, Martinez said.
"The interesting thing here is that there are debates in the World Intellectual Property Organization and there are demands from indigenous peoples that something has to be done. But nothing is being done."
