Love her. Would have bought Chaco Hipthong but couldn't find it and assumed they were no longer made. I would put 5, but compared to hipthong - 4. The attachment between the thumb and the nearest finger is not as convenient as hipthong.
Pros
I love blue color. The fit is amazing!
Cons
The straps never stay in place and need constant adjustment. When installed correctly, it feels good. It only takes about 10 minutes.
