Cozmo PF Water Resistant Slide Sandal (Women)

There is a suction at back arch area and makes a noise when walking. I would like to try to wear to see if my foot creates a shape in the sole and eliminates the suction noise but at this price it's a chance I cannot take. The leather is soft and comfortable out of the box. They are a little chunky. I got the tan color this time. Previously got the air color but returned due to the suction noise in the left shoe. I need a brushed leather insole to prevent slipping. These have a leather insole that I think would have worked even though it is not brushed or suede. With the foot problems I am having (spasms, numbness and pain) my old pair of this brand are one of the few I can tolerate. I prefer a backless shoe with a wider toe box, wish this brand would make.
