xsocks are expensive, and the airforce 1's are expensive xsocks. But they are the only soks that last, I normally wear them out quite quickly. Remarkably, the fit of the airforce is slightly bigger than that of my other xsocks (sun speed one, bk ultra). The difference is not big (definitely not 1 on the 1-4 scale xsocks use, maybe 1/2 or 1 on the standard US scale) , but noticable. I use them for anything in the winter when the low socks are too cold, and they are great. I have not used them enoug to see if the silver will prevent them from getting a funky smell over the years.
