HC Deb 30 September 1942 vol 383 c808W
Mr. Perkins

asked the Secretary of State for Air whether he will consider allowing air crews to wear shoes instead of boots while in the air?

Sir A. Sinclair

There is no rule that flying boots must be worn, but the practice in operational commands is to wear them because they give ankle support in the event of a parachute jump. In non-operational commands shoes may be worn by officers at the discretion of Commanding Officers.
