Wanted to stop tying my laces every now and then when they came undone. These things are easy to install. Mine came with a little installing tool but it's not necessary. I ordered another set in bitch for my boyfriend but his didn't come with a tool. No big deal. We both have not gone back to regular laces and just use them around the house for whatever needs to be fastened together with shoestring. They don't get caught or drag on the floor and basically your shoes become slip-ons which is great if you need to both quickly put on or take off your shoes. It is not loose and if so, there's a variety of sizes included in the pack which can be used to adjust accordingly. You may not need all of them but it's nice to have for other shoes.
