Swiftwick is where it's at. I've yet to see signs of wear on any pair after like 5 years. Better than Feetures for durability, in my experience.

Right??! I probably throw away two pairs a year of my most worn socks. My socks I buy for running and cycling last 5-10 years. I have socks I bought 12 years ago, going strong. Just basic nike athletic socks btw.

Try Swiftwick socks. I've used these for serious running/cycling (at least 3-4 days a week) and just anything generally active and have never thrown a pair away. Probably had them for 5 years, at least. Plus they do wool, hiking, and more casual socks as well.

I have one that extends to probably 15 feet that I bought at home depot. Seems solid. Gets so little use I'm sure it will last super long. Takes multiple attachments, very handy.

Fwiw, I've had two pairs of rainbows and both held up extremely well. Longer than my Reef's by a long margin. I destroyed the first pair of rainbows after 4 yrs of basically all day, daily use through college, but the second pair is probably 8 years old and going very strong.
