That is my point, keep it simple at first. Cadence is a much better heuristic than "heel strike". Also, it is understood you will run differently without shoes.
Jack Daniel's, (the famous running coach and physiologist) gave a good summary of it: There are two types of runners over time, those that adopt a higher cadence rate and those that get injured. Lore of Running (Noakes) and Daniels are both at complete odds about doing any significant adjustments to your running form other than monitoring cadence. At 180spm for most people that equates to a much lighter step that reduces the GRF (Ground Forces) per strike, which seems more important than other aspects of form.
