But, then the nations leading the committee wouldn't have advantages in materials science and analysis of fluid dynamics. The Olympics are aren't about the spirit of human competition. It's about which nation is better by count of medals.
Went to a ballet once. The male main lead was also showing pff. You could hear women snicker throughout. You'd think they would give him some other underwear during the break, but no. You could see a shading effect on the white tights. xD
They're not exactly high tech, but my wool blend socks have treated my feet just fine through many hot and often wet miles of wear. They're pretty frictionless inside my boot, they keep my feet from feeling wet even when soaked with sweat, and I don't think I've gotten a single blister since I made the switch. And only because you asked "where do I buy?", the Kirkland brand wool blend ones are my favorite.
Gotta love how they usually take more suggestive pictures of female athletes. This time the suits make the women flat as a surfboard, and the men less so lol.
