Rae, they are from endless, so I have a while. I often know right away when I adore something. On the other hand, the boots I'm replacing now, I only bought because they were a bargain and seemed useful because they were waterproof, not because I LOVED them. And then I ended up wearing them into the ground.
You are right that my head is a little off-kilter right now, so I think I'll let them stew a bit. Or steam, as the case may be. Thank you for that advice!
Angie's point is what I think is bugging me - the dainty ankle line. Apparently I like to surrender the ankle as well as the waist!
