Sketchers can’t be beat.
Size: 9, Color: Navy
What can I say? I love sketcher slipin's. They are comfortable and so easy to slip on and off. I have three pairs and would recommend them to anyone who has trouble putting their shoes on and off. They are well made and are very durable. They come in a variety of styles.
