Little Joe sneaker blooper

[Little Joe's horse]

Hi all, I remember seeing this on an episode of Bonanza - pre-internet, pre-AI on a color TV a million years ago. There was a scene where Little Joe walked into a room; it wasn't the Ponderosa, maybe a hotel or a saloon. Best I can remember, he had his full costume, hat, green jacket, etc BUT he was wearing sneakers- white sneakers if I remember correctly. I was a kid and I thought it was super weird. I remember he walked differently, like someone wearing sneakers would walk vs. someone wearing boots.

Does this ring a bell for anyone? Thanks.
