I'm okay with this. Isn't the point that men and women can wear anything, because the idea that heels are only for women is quite gender stereotyped?
Would be different if this was advertised or classified through the search index specifically as a woman's boot, but I don't think it is.
Not sure I gain much insight on how it will look on me from seeing it worn by a male model (eg, cut, calf height) but I can't get too worked up about this.
