I suspect you are correct. Certainly the late 60s and early 70s were very fluid and groundbreaking in terms of fashion, style and colours. I was certainly into flares, Jesus shirts, paisley and bandanas although I never wore platforms. Then, as now, I thought they were clumpy and disliked them. I do not really recall much about heels. What I do remember from that era, and which caught my eye at the time were girls in white go-go boots. For the life of me I can't recall if they had heels or not. I think they were just low 'normal' heels. I recall a very pretty red haired girl in my eighth grade class who wore go-go boots nearly every day, as did a couple of her friends. But her I remember in particular. I thought she was very pretty. And she was certainly very nice. I liked her boots very much too - and I wished I could have a pair just like them
This may sound odd, but I was a daydreamy kid with my head in the clouds and in those fairly unisex days I did not grasp straight away that these boots were strictly girls only - I mean, I knew that girls wore them, and I hadn't seen any on guys, but I did not grasp the strength of the taboo, not straight away at any rate, and so I very nearly came out asked for a pair for myself! Something or somebody clued me in - I forget what or how - and I was mortified to find I had been fancying boots that were strictly for girls. I felt as alarmed and embarrassed as if I had been inadvertently wanting to wear a dress.
Indeed I was so mortified that I buried this new discovered and unnerving partiality for what society deems to be "feminine" boots for decades. In that time my tastes evolved away from go-go boots to more elegant knee and otk suede boots, riding style, no heels to speak of. It was not an obsession, but when the autumn styles would come out and tall boots would feature once more in display windows and advertisements I would give a sigh and wish that it were possible for men to adopt the style.
