Eva outsole

Whatever adult style slippers you are choosing, you may want to add comfort and durability by adding an extra light rubber outsole to the bottom of your slippers.

This EVA outsole will allow you to walk outside with your slippers, in the garage or in the basement. It also brings more support to your feet. It is a very good investment, especially if you are opting for any of the closed-back styles as you will be able to replace the sheepskin insole when it wears out.  

Please consider that the EVA outsole will make your slippers feel a little more snug at first. Your slippers will mold to your feet after a week or two.
