Twenty-three-year-old Boot turned professional at Port Vale in April 2013 having initially been an academy player at Stoke City.
In a five-year career at Vale Park, he made 28 appearances, mainly last season, plus various loan spells at Worcester City, Norton United, Newcastle Town and Macclesfield Town.
Boot, who trialled with Fulham in 2013, is particularly highly regarded for his kicking ability.
In August last year, he started his first game for the Valiants and kept a clean sheet in a goalless draw with Oldham Athletic at Boundary Park, before saving two penalties to help Vale win the resulting penalty shoot-out.
He impressed new manager Neil Aspin and his performance against Wycombe Wanderers earned him a place on the EFL team of the week.
However, with Vale having two other contracted keepers, Boot was released upon the expiry of his contract in May. |
