L.T.
I made putting on shoes a game. I let him play with them when there was no expectation for putting them on. I would put my shoes or Dad's shoes next to them and talk about how we all wear shoes. I just didn't make it a big deal and eventually he started trying to put them on himself or let me put them on him for a little while. He did love his Robeez shoes so it was only harder sole shoes that I had a hard time with or anything new. He still resists new shoes but letting him play with them still works.
Hope this helps.
