Nude Shoes Dilemma: Advice Needed!

Way back at the beginning of the summer I impulse-bought on sale a pair of high-end shoes that I almost immediately regretted buying, for two reasons. First (most important) reason: they were not my size but a half size bigger. I wasn't loosing them but you could see a gap of half an inch between the back of the shoe and my foot. The SA talked me into wearing them with pads and I was stupid enough to buy into his sale pitch.
Second reason: they are a beautiful pair of shoes but not something that I needed and they are expensive, even on sale. What I really liked about them (besides the fact that they are nude without being pinkish or tan which is pretty rare to find) is the fact that they are very classic and they have a very low heel, which (to me) makes them the perfect pair to wear with non-black party dresses (as I am pretty incapable of wearing a pair of high-heeled pumps without looking, and feeling, like a foolish woman).
They are by Bally, a Swiss brand that is maybe more well-known in Europe:







I wanted to return them but the problem was the final sale policy of the store. Luckily for me I used my Amex so after getting back from my vacation I filed a claim through my Amex return protection program and I finally received the go-ahead from Amex to send the shoes (that must be unworn and in the original packaging), which is the final step before they can refund my credit card for the amount that I paid (something like $250).

But in the meanwhile I caved and bought the Elena shift dress (which is almost sold out on the website, as I just found out!) I have to tell you that I am still a little bit in shock about the price that I paid (even with the $25% off) but it's the "cool factor" of this dress that I find quite special and very suited to my personality/lifestyle and I thought that if I were ever to buy a lace dress it had to be this one.
So what the Elena dress has to do with my shoes? Well, the shoes happen to be the perfect pair to wear with the dress IMO (when I am not in the mood to wear it with my motorcycle boots, lol) because they are exactly the same champagne shade of the dress lining. And quite magically I tried them today and they fit like a dream (no gap). Don't ask me how's possible that a grown-up woman's feet grow up half a size in a few months but I have noticed recently that many of my old shoes feel quite tight. OK, now if this is a known symptom of incipient menopause, don't tell me!

So as I am ready to put them in the mail and never see them again, I am hesitating and I would appreciate a little help ;-). You maybe see something that I don't see and that can help me taking the right decision.
I am going to show you the shoes with the Elena dress but this is not a post on the dress itself as I didn't have time at all to style it (but I think that less is more with this dress so there isn't much to style). I am perfectly conscious that these are a more springy alternative to black tights/black shoes but I think that that's how I prefer it (without tights or with nude tights) and I don't think that there is a better pair of shoes for it out there, also because the dress is pretty short and a higher heel would create a disproportion. The downside of lower heels is that they don't lengthen the leg as, say, a 4" Laboutin.
But enough words, here are the pics:






What do you think? Should I keep them or you think that I can find better? The only contender would be this pair but it feels silly to return a pair of shoes that I already have and go through the hassle of ordering another pair very similar if it's not to save money (and these are basically the same price). Obviously I don't plan to wear them ONLY with this dress (incidentally I think that they should also look great with pants, even if I haven't tried) but this is the mean reason for me to keep them.

Your advice is greatly appreciated!
