I've discovered that some users here swear by wool socks for hot weather. I'd like to try this myself, but I wonder: are they are talking about regular ribbed socks or about socks expressly made for hot weather from a thin wool fabric? If the latter is true, then I'm having an hard time in finding them here in the UK. br> Also, I've read a wool blend of about 80% wool/20% synthetic recommended instead of 100% wool because the former allows the sock to be elastic. Do you confirm? Thank you.
