Hmm. I am not so sure.
"The store was so far away." would work as a response to something or as an explanantion why you did not go there, but not as stand-alone sentence in English. In general so ≠ very, it's more of an emotional amplifier, and as such requires an appropriate context.
So ≈ так/настолько.
Meantime очень=very, quite literally.
