True. Fortunately I only ever taught science at altitudes close to sea level, so there was minimal effect on FP and BP, but if you had to be really accurate, you’d still need to compensate for barometric pressure.

it is going to have little influence on your decision to wear sandals or shoes & socks

(and if you wear sock & sandals then I see no point in any further discussion)
