May I just add that there is no law in the UK that defines bare feet as illegal. There are no safety issues with driving a car barefoot. In fact barefoot is the same as being a shoddie (as shoe wearers are called) except for the absence of shoes. The danger of barefoot is the same like BBQ sausages where there may be a greater risk but also sometimes not. A naked person exposure: not so clothes can increase the risk of exposure by conducting core heat away from the body (at normal temperature ranges of course). When a naturist is cold his blood stays in the core,a textiles clothes keeps his skin warm which then allows that heat to be lost.

Having recently burnt my foot because I was wearing a sock and not barefoot there is a greater risk in being shod.

Did Steve not get on the plane textile and arrived at airport and then undressed on egress? Need to check that but what greater health and safety risk does a naked person pose? Unfettered testicle in the eyeball 😕
