Comfortable socks that work well with flip-flops.  I have a wide foot, tho, and they are a bit snug.  Not uncomfortable, and I'm going to keep wearing them, for sure.  I just wish one could find larger socks of any kind for the wider foot.  I'd also like to have to choice to order a 6-pack of the black/gray  only.  White gets dirty so fast, especially when wearing the outdoors with flip-flops.  When these wear out I will definitely look to purchase them again from this seller.
