If they were men's or unisex-style boots and the heel was only (as stated) a 2" cuban , I would scarcely expect them to attract any special attention or comment. If they were of a more feminine design and/or the heel was significantly higher or thinner, then they would likely make an impression, if noticed at all, but not necessarily lead to comment.
I have often worn my men's cuban-heeled boots like these, with a pointed toe and a 2.7" heel. I expect they 'registered' with some passers-by but I've never had any obvious looks or comments - except from my wife, who dislikes them!
