I have a LOT of problems with my feet.  I have just started using them, but I really don't have many shoes to use these in, yet.  I'm so used to wearing sneakers because I have custom othodics from the doctor, that I haven't been able to wear other shoes.  The ones from the doctor are thicker so I need a shoe that won't slip off of my heal.  These you can wear in other shoes, but I don't own the "fun" shoes now...yet! :)
