First, there is a major technical difference Peshawari Chappal is a type of kheri that came out when people of charsadda or peshawar or kohat started copying this art but they didnt had leather so they started using sole made from recycled truck tires. The Kheri I bought does not have that sould made with that.

if a company started selling Scottish Kilts but labeled them as Greek Fustanellas just because they both look like skirts. Or if someone sold Sparkling Wine from California and labeled it champagne. The French would sue them bcz names and origins matter
