Thank you very much for your input ladies!
Scarlet, actually all the potential pairs (4, 5 and 6) have a small wedge. It is a hidden one one in #4, an about an inch tall, but it is there. That is precisely why I chose them. And I do have some older shoes with higher wedges that are comfy, a bit worn, but cans till serve for at least a season.
bj1111, I would like to get all 4-7, but not sure if it will happen. #5 are the first ones to get next, so those are for sure. Between #4 and #6, #4 would be comfier and #6 has more visual impact, so it kind of a tie. The sandals, #7, I would get for sure too, as I need something to wear out of the lab too, and he summers here are really long and hot. Plus I have't gotten any new sandals in the last two summers.
Shannon, Asters are super comfy from walking around the apartment, they are nicely padded. When it comes to sizing, I am normally a 8 but go with 8.5 sometimes in flats. These are 8.5 and there is a bit of room in the toe box, 8 would have probably worked too. But since they have this hard cap toe, I am going to err on the side of larger as I do not want my toes squished.
