I'd be careful. Unnatural ratios can be very noticeable, and body ratios are very ingrained into our subconsciousness. It would cause something to feel off on a first glance, causing a more accurate second glance, which likely would it make very obvious.
It's not exactly this but have you considered barefoot shoes? They have a super-thin sole so they naturally take some height off you, compared to "normal" shoes. I wear them for completely different reasons (as a cis man who has found these to help with feet pain and posture after being a kid with flat feet), but I thought you'd appreciate the tip.
Groundies make them with "normal" looking soles, but it's all an optical illusion - they have a strip around them so the sole looks "thick", "normal" and "fashionable". Essentially a less exaggerated version of that drawing:
Caveat: they're more niche and therefore expensive. Also not everyone enjoys the idea of walking without cushioning and feeling the texture of the ground.
I had Converse shoes in the 90s and that was already very painful if you stepped on a little rock on the ground. I can't imagine going even thinner than that for outdoor shoes. And at least the one in the picture look more like indoor shoes / slippers too.
