Ok product. It's very easy to install: you just put it in  and then pull. Don't worry about breaking it and everything will go smoothly in a few minutes. It comes with various lenghts. What I dislike : the color and texture make it look a bit juvenile and if by any chance your shoes are just a bit too big, it won't be as snuggly with these and your foot will be a bit too loose and will constantly rub against the shoe(which it would not with shoelaces).

Cute product, nice for sneakers you would use at home or maybe at the office. But I would not use them to walk outside.
