Although I consider spending $50 on six pairs of socks of dubious quality insane, I do wear expensive socks (but I don't pay for them). Socks are my go-to gift request for those in my life that insist on buying me presents even after I've worked to dissuade the practice amongst adults. For those that accept utilitarian gift requests, I request sturdy hiking socks, such as Smartwool or Darn Tough (they can run up to $20 a pair if one doesn't watch for sales).
For those that insist on "fun" gifts, I have styled myself as a sock collector/fan so they purchase me socks with fun designs. These gifts really ARE fun, too, as people try to find the perfect socks for my interests, personality, or an inside joke we share. My feet are always colorful, important for mental health in the gray PNW, and I haven't bought myself a pair of socks in decades.
