A cobbler is a tradesman who mends or makes footwear. The occupation of sandal maker shares many of the same trade skills.
The Tal Shiar files on Garak mistakenly believed that he was a cobbler. When an operative was contacted in 2371 by Benjamin Sisko, he corrected the operative and told her that Garak was a tailor, she told Sisko, "I'll correct our records. That is, if he's still alive." (DS9: "Improbable Cause")
In 2373, a Takarian sandal maker approached the Great Sages to request financial assistance. Describing himself as "a sandal maker from the poorest quarter of the city", he proceeded to tell the Sages that his "sandal shop is failing," and that he "can no longer feed [his] family." When the Great Sages, who were actually two Ferengi that were exploiting the Takarans, discovered that the sandal maker was not exploiting his family as free labor in his shop, they offered him a copy of the Rules of Acquisition, rather than the food and medicine that he requested.
