You could try this instead. $23 for 7 pairs.
If you want to go with the cintas route, you have to call them and order them over the phone. They are way over priced anyways and there is no gaurantee you won't get those crappy glued on UPS logos.
have you had anyproblem with theses wearing out fast? i bought some of those bobby sox and they lasted for a long time. just curious
