These laces are pretty easy to set up and once correctly in the shoes, work fantasctically. I have some foot swelling and these end up being a LOT more comfortable for me than regular laces.  I love these laces and am considering putting them in all my lace-up shoes.  I highly recommend them to anyone who wants to make their lace-up shoes a little easier to get on and off and/or need a little give with the elastic laces.
