I wore these on ONE trail. Many people swear by them, but I'm happier in my hiking boots. I will say that they match anything ;), didn't rub any blisters, and get a lot of compliments. There are a lot of fun blogs featuring the many fans of these shoes, and a lot of really fun information, but I didn't know if I could post any links. These are Jerry Garcia-inspired, for a start. ;) Btw, I'm a female who wears a size 9. These didn't come in half sizes (they may now), so I had to round up from my usual 7.5 men's shoes, which I prefer to women's shoes 100%. They were a tiny bit big, but nothing bothersome. Probably would be perfect for a 9.5 woman's. From the website: The 1025177 KEEN Men's UNEEK Sandals make a simply bold statement, with solid-colored cords and a matching sole. The one-of-a-kind cord construction molds to and flexes with your foot for a custom feel, and the soft footbed kicks up the comfort factor. The razor-siped sole adds stability on slick surfaces.
