AFAIK (spouse is an OT, works with PTs, puts up with my barefoot nonsense & enjoys explaining biomechanics to me) forefoot walking is something to avoid. Leads to shortened calf muscles/tendons, can lead to problems in old age as balance degrades.
There's also some interesting anthropological work by Esther Gokhale about gaits in indigenous peoples indicating that heel-first walking is natural, but very different from the gait induced by cushy shoes - no slamming on the heel, place the front heel on the ground while the back foot still supports all of your weight. She does sell books and workshops, but I found her book at the library, tried out the exercises, seemed legit.
Anyway, YMMV! Don't take my word for it; check out the primary sources, etc. If forefoot walking works long term for you, then go for it - one of my in-laws only walks on her forefeet /shrug.
