I just discovered Fit Flops a few weeks ago. I started out with my regular size (8) in the WalkStar II I think (with smooth leather frontal thong) and because they were so loose, I fell down, busted my knee. So, I returned them and ordered this in the 7 which works perfectly for me because my feet tend to be on the narrow side. I have trouble with sandals in general and keeping my balance with them on, but I have adjusted and find them to be like a second skin. I cannot believe that it's taken me 63 years to find a shoe so wonderful! My Acupuncture physician recommended them because I have plantar fasciitis and I while wearing these I have NO pain. I since have purchased the Gogh suede clog in a 7 also and it is likewise an awesome fit! When you first try it on in the smaller size, it seems too short, but it stretches in a day or so. I had also purchased the Gogh in patent leather with the studs along the outside, but it was an 8 and seemed so much bigger and wider. I wasn't sure if it was worth the money to invest in the 7. Hope this helps someone to make decisions on size selection.
