Low liners are about the most comfortable liners available. They are super thin and provide a comfortable layer between your foot and your show without adding any thickness. The silicone on the back heel assures you that they won't slip when walking or exercising. They work great with deck shoes, tennis shoes or any shoe where you want comfort but not bulk. There are two styles with each set and this one includes a black pair with fun words " laugh lots" and the other pair is white with "be happy" They wash great and are a must have for spring! Enjoy!
