These are simply contoured rubber strips that plug into the shoelace holes in your shoes.  They look pretty much like shoelaces even close up.  They work pretty much as advertised, allowing me to slip on/off my work sneakers with little difficulty.  The only problems are that the rubber "laces" are in predetermined sizes, so you have to play around with them a little to get them to work right (as displayed on the cardboard form they are too tight.)  Also, it's a big pain to get them through the lace-loops on the tongue of the shoe.  Also unless your shoes have a loop at the top of the tongue (and I don't think any do) you will have to pull up the tongue when inserting your foot.  My feet are wide, and wider laces would be better, but these are JUST stretchy enough to do what I want them to.
