These are inexpensive and comfortable sandals for my 3E+ feet. I have a third pair! The tread seems to wear out a little quicker than I'd like. I have my previous pair. One outside, the other inside.
Pros
My second pair. Very comfortable but due to the material you can spray them with deodorant.
Cons
Flip flops may not be appropriate for people with plantar fasciitis or other foot conditions.
