I have a skinny, narrow heel, hard-to-fit foot. I really loved the look of the Space Hippie even though the heel back projected out from the back, a look I don�t like very much. I generally take a 9 or a 9.5. I ordered the 9 from Nike.com in the Cargo Khaki /Sequoia Photon Dust/Pearl White. The overall fit was perfect, and I really wanted it to work, but no matter how I fiddled around with the laces, I just couldn�t get the shoe to fit right. My heels kept slipping out of the shoe as I walked. So I had to return with regret. A beautiful, elegant, lightweight, comfortable shoe.
However, at the same time, I also ordered the Free Run Women�s Road Running Shoe in a 9, this in the striking �Ocean Cube� color, and I hit paydirt. The shoe is a perfect fit plus it�s extraordinary looking. Just went back for a pair of black. It�s a lightweight shoe, perfect for what I want it for which is walking. I don�t generally like the style where the heel projects out from the back of the shoe, but it seems to be okay. It�s my first experience with a shoe that has no separate �tongue�. Instead, it�s all of a part of the fabric. So there�s no tongue slipping sideways.
Thanks to those people who take the time to write reviews with sizing information. Very helpful.
