Did redd foxx really walk like he did on his show Sanford and son?

Yes, Redd Foxx did indeed walk like he did on his show Sanford and Son. The limp/shuffle gait was a part of his stage persona, and he had been performing it for many years before the show was created. In fact, the distinctive gait was one of the reasons that Foxx was chosen for the role of Fred Sanford.
