Hi Geoff, of the pre-Complete Workout videos, only the original, the Pregnancy, Birth and Recovery Workout, and Start Up were barefoot for the entirety. The other tapes all started with shoes then removed them for the floor work, as it allowed more mobility for the feet during those exercises. I think after the PBR tape, it was deemed more important to wear footwear, especially during cardio. One of my VHS copies of the original Workout is actually a version that came out before it was removed from circulation – the Karl Lorimar intro is dated 1985 at the start. The same Workout, but several movements either removed (no “swing through” in the warm-up” and the last two leg split stretches at the end of the buttocks through the high shoulder stand are removed completely, to name 2 examples) or dubbed over (like ”press” dubbed over ”bounce”). There is an over-voicing added to both aerobic sections saying ”you should have your aerobic shoes on now to give more cushioning and support to your feet.” No one I’ve discussed her tapes with has seen this version and the DVD retained the original version of the Workout.
