I've wearing them now for about 2 weeks now and like them more every day.  They been put to test on days hot days we're having and all I can say is they keep my feet dry and comfortable even if my body is hot.  I ordered a pair of wides and that extra space makes  a big diference.  I've always wear D's and mi little toe is kind of hit against the side, now that I have tried this wides  I 'll be ordering only wides fron now on.
