I have been a fan of curly shoelaces for quite a few years.  I love them because my shoes are never too tight but they are always secure.  Once you thread in the laces and adjust them to your particular comfort level you never have to worry again, unlike tying shoes every day.  Another big plus is you can EASILY slip your shoes on and off.

They are becoming hard to find in stores now, so Amazon was the place to look for them.  I even held off wearing a new pair of white athletic shoes because I needed new white curly laces before I would wear them!
