I use a pie shield with each pie that I bake. I routinely slip a shield over the crust every time a pie or crust goes in the oven.
Every Thanksgiving, when I made pumpkin pies, I carefully arranged pieces of tin foil along the edges of the pies to keep them from burning. It didn't work very well. Pieces of foil fell off or dropped into the filling making a mess. You can avoid all that. Just slip a pie shield over each pie before putting it in the oven.
These really are perfect pie shields. They're durable and reusable. You can stick them in the dishwasher. The light aluminum color reflects heat. They have a turned down edge to protect even the edges of your pies.
Because you invest so much in your pies and because your pies are the crowning touch of your meal, don't risk baking pies without a shield. Get a pie shield for each pie that you bake. If you bake three pies at once, you'll need three shields.
