It’s like alignment on a car. In car terms it’s toe in and toe out, which refers to whether the wheels are pointed straight ahead and parallel to each other. That’s what I think you have, some toe out. Orthotics won’t affect that.
Camber is whether the wheel is vertical. If it’s not, your tires wear out on the inside or outside. They use so-called shims to fix camber.
Orthotics are like those shims They fix the vertical alignment of your ankle.
