I have purchased the Hickies in both black (for my boyfriend) and white (for me). He wears his in size 10 Sketchers and has been wearing them since Christmas. He loves them for the ease of slipping his shoes on and off before / after kickboxing but they still keep his shoes snug for walking the dog and casual wear. I wore mine for 2 weeks walking almost 180 miles in women's size 7 Dr. Scholl's. Again, they kept my shoes snug but made taking shoes on and off very easy. Unfortunately, I wore my shoes out with all of the miles and my Hickies were filthy. Fortunately, my Hickies look like new with a little hand soap and water. They are ready for their second pair of shoes.
