I am very disappointed in the quality of my new UpBov sandals. I have been wearing them indoors as house slippers and the outer “skin” is already wearing off. I have been wearing another brand (Oofos) in a similar style for several years with no issues. Even though the sandals are comfortable, I do not recommend them. At this point, I am very disappointed in Gravity Defyer and will look at other brands for this type of shoe. That being said, i am very happy with my new pair of Mighty Walk shoes. I have purchased a total of four pairs from G-D through the years.
