I love Vibram, I already have at least 15 pairs (mainly because they wear out so quickly!) and I was intrigued when I saw the new Furoshiki model. I think I bought them with the wrong intention, I was hoping they would be more versatile but they are more suitable for indoor shoes. You can't go very fast because there is little support in front of your toes, it's a very weak little pocket and your fingers slip a little. Overall, I really like these shoes, but I wouldn't buy them again. They are unique and very comfortable, just not very functional outside of slippers.
