I'm a big adidas guy so that Nora shoe got me digging through adidas's back catalog. The upper is definitely straight from the Nastase super, with a different leather toebox from another adidas tennis shoe from that period, possibly the player GS. A lot of those tennis shoes from that period are similar, which is probably why people are drawing rod laver comparisons.
The back of the shoe is definitely unique, I don't recall a shoe with the same style. The outsole of the shoe is really nothing I've seen before. Typically adidas outsoles have a faux welt, yet this one is completely smooth. The closest comparison is really this ATP shoe which dates roughly at the same time the Nastase release
That being said, this shoe's outsole is probably unique.
