Minty has visited Ponyville and she decided to give gifts for Hearth's Warming Eve. Minty being Minty (basically a G3 version of Pinkie Pie), she has given everypony socks. That was her shtick in the G3 series, a great love of socks. The series may have been awful but she was the one interesting character in it, who knows what fun she be with the right writers and the G4 universe.
Especially with her and Pinkie.
