Toe point normally will be about 30 degrees with heels at shoulder width, and increases in angle with stance width. The critical thing is that the knees operate parallel to the toes so that the patellas track straight. So even with a shoulder-width stance the toes can point out a little more as long as the knees follow the angle. On occasion, a person will be pigeon-toed or duck-footed, and will not display normal parallel foot/thigh geometry in the squat. This must be taken into account when analyzing toe position.
