I bought these socks for the winters in Chicago.  I've only worn them a few times, once on a 6 mile walk and they were comfortable and didn't fall down.  They've also held up very well in the wash.  If they hold up as well as the Men's Ironman Thunder Pro Socks I have for warmer weather and indoor work-outs, I'll be a very happy camper.  In my opinion I think Wig-wam makes a damn good sock.  Wish I had known about them years ago instead of wasting time on Hanes and other junk socks.
