The duo teamed up to promote a new empowerment campaign for girls.
Swift said in a statement: "I'm so excited to be partnering with Keds. I've been a fan of Keds for years because they have two of my favourite elements of great style - they're classic and effortless."
The exclusive collection will be available from October 22, coinciding with the release of her new album Red.
Swift previously revealed that she doesn't like to drink alcohol or to "hook up" with men.
She explained: "I don't drink much alcohol. If it doesn't taste like candy or sparkles, I usually don't drink it."
Swift, who is dating Conor Kennedy, also said that she prefers to fall in love "really fast" than to get into casual relationships.
