Thanks for responding so quickly!
OK, that's great to know that the Naturalizers are so comfortable. I'm attracted to them because of the low vamp and the lower, sturdier heel compared to a lot of the strappy stilettos I've been coming across. I'm also less likely to scratch the heel up since it's wood instead of covered leather or silk.
The AE wedges are pretty and were very comfortable, and if I were a wedding guest I wouldn't hesitate to wear them. There's also the cheap price as an incentive. With a shiny satin dress, though, I'm a little worried that wood wedges would look too informal, whereas the Stonehenge color of the Naturalizer slingbacks might make my pasty white legs look long and lean.
I'm thinking about ordering the Naturalizers just to see if they work, and if not, the AE wedges can always be a backup.
(Anyone else have an opinion to share?)
