Dad's Army (1968)

Season 4: Episode 3

Dissent in the ranks follows after a foot inspection as a result of which Mainwaring decides the platoon need their feet toughening up and proposes barefoot football as well as a 20-mile route march. To prevent the march, the men hatch a plan whereby they will go into the shoe shop from where Mainwaring has ordered his new boots and substitute a size smaller which will pinch his feet and put him off the idea of a long march. What they had failed to appreciate is that he already had a pair in his own size in for repair, which the shoemaker returns to him before the march.
