Chaco sandals are good for people with problem feet but they can be problematic for people with bunions or big toe problems, the fastening strap can cause a bit of pain, especially on moderate trails/hikes. Step into this model with a snug but comfortable bootie that's almost good enough to clip a large Chaco insole to your feet. The straps help secure them further in more moderate terrain, and unlike standard sandals, they can be loosened appropriately to pull them in even more without causing as much discomfort as strappy models. The arch of the foot will appear high if the heel is not positioned correctly. . Push it back barely noticeably, but it's the best insole, recommended by more podiatrists than any other.
