I actually tried these on today at Saks in black, they are actually very uncomfortable. But that probably won't stop me from ordering them in nude anyway.
The thin strap was digging into my foot. But I should comment that I was wearing tights today, although it was 65 degrees in NYC, so it is possible that they were uncomfortable due to the tights.
I also tried on the nude patent leather joli noeud and those too were very uncomfortable. That is a great shoe and a great alternative to the nude patent leather yoyos, but for me at least, they were very uncomfortable and I very rarely feel that way about CLs.
