Low liners are about the most comfortable liners available. They are super thin and provide a comfortable layer between your foot and your shoe without adding any thickness. The silicone strip 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 nautical theme with a blue anchor on white and a sailboat on blue. They wash great and are a must have for spring! Enjoy!
