be/stand to one's sock

Would you tell me whether I am right with my interpretation of the expression in bold in the following sentence?

He stands six foot in his sock. He is of six foot height.

Thank you for your efforts.

It would be ‘socks’ not ‘sock’, but yes, he is six foot tall without his shoes on. (With shoes he would be slightly taller because of the soles/heels)

Hi Beeesneees,

Thank you for your amendment.
