It seems that US people only use "sports" not "sport".
But why do people (both American & British) say "sports shoes", "sports club", "sports team", "sports bar", "sports facilities", etc?
But "apple juice", "orange juice", "book club"
Why don't they say "sport shoes", "sport club", "sport team", "sport bar", "sport facilities", etc?

Sport is a singular noun ("a sport"), whereas sports is not only the plural of sport, but also by convention refers to the general category of all sports. Example: "Tennis is a sport. Tom likes sports, but Harry only likes one sport."
Regarding phrases like "sport(s?) shoes": the way it is usually spoken, you can't hear the difference anyway, so the question is a bit esoteric. BUT the "correct" version (in AmE) would be sports shoes because we are talking about the category of sports. If the shoes are intended for one sport only, then you would say the name of the sport: "baseball shoes".
