I have larger calves, but some of the regular Sock-it-to-Me socks fit, anyway.  I have several pairs, now, both wide calf, and regular.  Most of the wide-calf ones are just slightly big, but only two of the regular pairs have been too tight: This pair, and the pair with the black cat and the fish bowl.  I was terribly disappointed.  They seemed like nice, quality socks, but meant for those with more slender calves, I think.
