I bought these for my 19 month old son's shoes and they save so much time and hassle. My mother in law bought him really nice new shoes that I loved, but the laces were a huge time drain because I had to wrestle with my son to get them on and keep him still while I tied them. Just pull these tight and you're set. 4/5 is because they were a little too big and I had to tie and rig them to stay short enough not to trip him.
