While that "may" be true to women, I can say that to 99.99% of men I've known (including myself), the difference between a $2,500 pair of women's shoes and a similar style shoe from a discount shoe store is unlikely to be noticed at all. In fact, I can label women's shoes into "flats, open toed/open foot, heels, and boots" and anything that fits in one of those categories without being extravagant in some manner is going to be thought of like any other shoe in that category. I've never looked at a woman and said "wow, those shoes really make her more attractive to me" and I'd wager the same could be said for most men.
