My pair arrived today, and my dh conveniently forgot that he told me I could order them. So just to show him that I'm not a child and can order whatever shoes I want, I wore them today on a mile and a half walk. I normally wear my Capris or Athens, so I thought no problem with the Ithacas. Here's what I noticed:
Definitely thinner at the toe.
Definitely thicker at the heel.
Almost feels like walking on a high heeled flip flop.
Rubbed blisters between my toes, but I did that when I started wearing my Athens again this Spring, so not sure that indicates anything other than that the post on these doesn't sit in the same places as my Capris or Athens.
I think they have the potential to be really comfortable, especially if you're someone who puts a lot of weight on your heels. Mostly I need to get my feet used to them. But with less than 2 weeks till our trip, I might still to the Athens and Capris and leave the Ithacas home.
