Foden's desire to play scrum half saw him sign for Northampton Saints on the basis of a promise to play him at his preferred position; a promise that Sale Sharks could not give him,[5] considering his strong performances at full-back, and the club presence of England international scrum-half Richard Wigglesworth and the arrival of Welsh international Dwayne Peel for the next season.

[8] In March 2011, following a Saints win over Wasps, Foden was arrested following an altercation with a taxi driver in London, but both Northampton and the RFU were happy to let the issue lie after he accepted a police caution.

In May 2014, Foden won the Aviva Premiership title with Northampton, playing 80 minutes plus extra time in the final against Saracens at full back and scoring a try.

[14] Despite fullback Delon Armitage being injured for the 2009 Investec Autumn Internationals, Foden was not included in the squad – manager Martin Johnson instead preferring to play wings Ugo Monye and Mark Cueto out of position.

[16] Foden retained his starting place for the summer tour to Australia, playing with club colleague Chris Ashton.

[19] Later that year he cemented his place as England's first-choice fullback, his early flirtation with scrum-half shelved after some strong form.

Foden was a key member of the side that beat Australia twice in 2010 and also started all of England's Six Nations games as they came up short of a Grand Slam in 2011.

In October 2019, Foden was a contestant in The X Factor: Celebrity as a member of the group, Try Star, alongside Levi Davis and Thom Evans.

[20] † Full international cap not awarded for Barbarians Test match [14] Foden married Una Healy of girl group The Saturdays on 30 June 2012 in her native Ireland.
