what I had been wondering! Of course I have never seen or felt the hot sock, but after feeling the one at Sally's, I kept wondering how one's hair wouldn't stick to it?? Thanks, that's what I wanted to know!
The sock thing should never really touch your hair - at least I don't let it touch my hair when I use it - just aim it at the hair and scrunch.
To be fair, the only diffuser I've ever used is the sock/mesh kind - I've never tried the bowl kinds, so I have no way to compare them.
