Yeah, I didn’t see that ended coming.
Getting serious for a moment, I would say: never underestimate the importance of socks, as well as athletic shoes and insoles, in competitive sports.
Yeah, special tools for special jobs. In serious biking you wear very rigid, cleated shoes, some prefer to term them boots, that barely flex at all. Not unlike ski boots in that regard, and you can barely walk in them.
Can you wear any loose, white cotton ankle socks? Sure, but not as comfortable if you're biking for a longer period over a greater distance. A bicycling sock is optimized to the task.
With wicking material to keep your feet dry. as wet skin is prone to blisters. Thinner, since they don't need to perform impact cushioning during walking or running. More like men's evening dress socks, or perhaps peds are the better comparison. Yet they need to be tough, full elastic to stay snug, and cool when you're body is sweating and needs to lose as much heat as possible.
And I like them being easy to dry, since I always air dry mine, not wanting to put them through a clothes drier. In fact, sometimes when out for several days I've sink-washed them in the hotel, along with my other quick-drying specialized riding gear.
And really that can be typical of almost any sport. Specialized gear that's built to meet that specific task. Golf is that way, for instance.
My golf polos are likewise more expensive, because they have special features. Much greater length, for one thing, so they don't pop out of your waistband and give you plumber's butt, when you squat down to gauge a putt. Or as you lean down to tee-up, or to retrieve your ball from the cup.
Made of special lightweight, ultra-cool moisture-wicking fabric, yet most with an SPF-50 rating against the sun when out on the course. Golf caps can have those features, too, not an ordinary logo cap, although some golfers choose those, anyway.
My golf shorts are also incredibly lightweight & cool, with beautiful satin-taped seams like in fine dress trousers. But also tough, and with deceptively generous slash pockets for balls, glove, a special small pocket for tees, along with other adaptations. My tennis shorts also had almost trick pockets that could accept at least 2 tennis balls, despite their brief, snug style (back in the day).
