I got Vibrams, which I love, but the foot odor without socks was ruining them.  I know you can wash the Vibrams but that wasn't working out either.  I tried the toe socks and they are awesome.  I wear them with my regular asics to run as well.  I thought the extra material between my toes along with the vibram material was going to be bothersome.  I don't feel them at all OR smell them!  I wish the toe socks were cheaper.  $10 per pair is too much.  The lightweight toesocks do seem to have some thread at the toes coming out. The medium weight toesocks have held up really well with asics.  Though they are too thick for vibrams.
