Think of it this way. When the skis enter the fall line, they accelerate. You need to be ahead of the skis so that they will "push" you instead of pulling you. If your weight is on the heels, you're going to get pulled. If you start a turn with your weight moving forward onto the balls of your feet, that will let you get ahead of the skis. If you finish the turn letting the skis catch up to you (e.g. weight over the arch), then you have room to move forward again to start the next turn. Ski bindings and boots are designed to set you so that your toes are below your heels so that you can easily move your weight a little forward. Too much or too little and your going to have problems. There's a fair amount of "wiggle room" that won't make much of an impact for most skiers. Some skiers need adjustments to get their set up to match their body configuration. Many skiers ski in the backseat because of technique. Many skiers ski in the backseat because of setup. The only ways to know for sure which category you fall into are to get checked by a bootfitter or get a lesson from a pro who knows alignment.
One of the adjustments for custom footbeds is to "build up" the thickness under the toe or the heel to effect fore/aft balance. It may seem weird, but some backseat driving can be cured by "toe lifts" (building up under the toe instead of the heel). Other times, heel lifts are needed.
Canting is an adjustment to change the lateral balance. People who are bow legged often need canting under their little toes to get their feet to be flat when the skis are directly underneath them. Canting changes how you to have to move your body to get your skis to change edges.
