Assos spring/fall socks are to your feet what Patagonia silk boxers are to your tush, we kid you not. They're our favorite socks in the whole wide world because they're light and they magically conform to your feet without bunching or wrinkling -- no matter how bony your feet are. Their dense, tightly-knit weave makes them feel more like dress socks than anything cycling-related. Other than a small bar of top-notch Swiss chocolate, this is perhaps the best sub-$20 indulgence we know of.
