I bought my first pair of the aireators maybe 8 or 9 years ago and they're still going strong. They don't even look worn nor have lost any elastic. I've added quite a few more since, including other brands, but the ones by defeet are the best. Lin socks have a thick uncomfortable seam which I can't understand how it got past their R&D. Don't know if others have noticed, but the cycling socks don't pick up the dirt like regular cotton socks do. I go out on my mountain bike and get my socks all dirty but one washing later, they look great. Yeah, the aireators are a bit pricey, but when you can get as many years out of them as I do, with no end in sight, then they're worth the money.
