Huge thanks, everyone! This is helpful. Heck, just the process of putting on each pair and snapping a photo was helpful. I'm ready to pass along a few pairs now.
Interestingly, Angie, I'm not ready to give away the EF sandals yet. I got those last year and find them really useful for very casual days with lots of walking -- they're sturdy and really casual but substantial (and not slip-ons), and a really versatile color, and sometimes that's just what I need. I'm not sure what an updated version of that would look like, but I'll be keeping an eye out.
In fact, that's my trouble with this whole sandal thing -- I'm not totally sure what updated versions of some old favorites should be! I'm kinda over those old Cole Haan thong-style sandals (but big props to CH for really well-made sandals that have lasted through 5 years!). But I don't see anything out there that makes me go "ooh! that's it!" Maybe it's not a good season for sandals because everything seems to be about mules.
Speaking of which, Angie, no, no mules for me yet. I find them cute when I see them in photos but I'm unsure about them on me, with my summer wardrobe, and with my flattery priorities? (I'm a little unsure about how they look on less-than-fab legs) I've tried on a couple of pairs but quickly determined they did not work for me -- either not comfortable, bad fit, or they looked odd. I guess I'm just not used to them -- I have memories of walking out of them, and sweaty feet. I suppose I need to try some on.
