I bought these and a different type of Keens to choose which I liked better. Well, I can't choose, so I'm keeping them both. These ones were pricey, but I love the way the sole comes up over the toe, and the squareness of the toe. They really are comfortable, though I haven't walked alot with them yet. The heel was really really stiff, but after massaging the back of them a bit they were better. I have a size 5.5 (us) for anything that has no laces, 6 for sneakers and boots. 5.5 worked great for these shoes though I'll have to wear thin socks with them, but I really think a size 6 would have been too loose. The green isn't bright, its really like a shadowy gray green and they look great with jeans! I gave it a 4 star rating because of the heel and how expensive they were.
