they arrived in 2 days! so far i love them. ive only worn them, twice though, so we shall see if they hold up. i wear and 8-9 womens and i bought a medium and they fit great. they aren't "seamless", but the seams aren't horrible. i have a real issue with seams in socks and they sometimes bother me because the seam goes down the center of the toes on the sides. i got them for my 5-finger shoes and they really help get the shoe on and i think this will help with odor and bacteria and fungus (athletes foot). lets hope they last.
