Socks and underwear are the two things I'll dish out some money on for quality.
From my experience, the best kind of socks are ones that have at least 70% merino wool. They are great for both warm and cold environments, comfy af, dry fast, and are anti-bacterial. They also are super easy to wash and air dry way faster than any shit quality sock.
The best quality I've ever found and exclusively use are People's socks. Never really cared about my socks until I experienced the magic of some quality socks. You can find them on amazon. Just search "peoples socks merino wool" or some shit. Like $25 for a 4 pack.
On that note, stop using shit quality underwear, or any cotton underwear for that matter. You're just gonna have perpetual jock itch. Buy some quality underwear with micromodal or spandex fibers. They too are anti-bacterial, dry fast, easy to hand wash, and comfy af. Buy some good quality underwear/socks and save yourself money in long run on fungal medications.
