It is good to use it at home. I am using it at a camp where we share showers.
Pair are good when used at home. Not when used in public showers because the openings are too shallow where the dirty water soak the bottom of one's feet. But that was my fault. I should've been more careful when I looked at the pairs' dimensions.
Pros
11 x 4 x 2 inches
Cons
May not provide enough cushion and support for people with foot pain
