These are by far the most comfortable flipflops I've ever worn... and also by far the most expensive. However, I'd gotten to the point where I didn't wear flipflops at all anymore because my feet would hurt so much... so I'd rather have this one high-end pair that I can wear all day long and to walk in, instead of 5 pairs that are somewhat torturous. I also like that there is a wide range of colors.
The one thing I find "off" about them is the sizing. I typically wear a 7, occasionally a 6.5. In these, the 7 was way too small and since they don't have half sizes, I had to get an 8. Overall though, I really like them and think it is a good investment.
