Did you ever notice?

With the amount of pot smoke always billowing out of the van, it's not surprising that he forgot to put on socks.

Maybe it added to Shaggy's beatnik/hippee character? Who knows...

I actually noticed this recently when I watched an old episode.

A lot of cartoon characters were made like that, I noticed it with Brutus in the Popeye series also.

Why I don't think I ever noticed him not wearing socks how did you?

I never noticed. Probably because of how fast paced the show is. And that's not a bad thing.
