Practice the process of getting a shoe on and off. If your child goes to a Montessori School, they probably wear slippers during work time, shoes outside. There's a lot of shoe transition, imagine how much practice it may take for independence! Anything to ease the morning madness of getting a family ready for the day is always a treasure, no matter where the child learns.
Show the child how to open up the shoe wide enough for the foot to enter. Use language while instructing, "this is the tongue of the sneaker, these are the laces, this is the sole." I like to put of plenty of lacing, bead stringing, and tying materials in September with this aim. Learning to tie takes a while, but starting while the child is a good idea.
