Am so sorry about your sister and her husband, Galiana!
Thank you everyone for your feedback on the boots and for the Camper link. The Camper ones indeed look very similar to SN (also sold out or not stocked in 42). The key thing here would be the fit - how wide is the shaft, how high, etc [I do remember historically having some Camper boots, they did well]
In terms of the shoes discussion. I'll try to be profound here :) I very often like my clothes not to put an obligation on me. I think how we dress is connected to how we are as characters. I am an introvert and social communication is work for me. If clothes speaks louder than I want, I perceive it as extra communication I have to do and it can be taxing. Obviously at times, you want to make statements, but other times, I don't want to be obliged to anything by my clothes. That's why my favourite everyday wfh clothes is well selected Margaret Howell. It is perfect, it doesn't demand anything, her clothes (well, at least some of it)
I experience shoes then as even more a demand put on me. Not only what the shoes say when they speak, but also a physical demand in how they impact your gait, ability to move freely, run if needed, etc (this can be true of the clothes, too).
So basically I want is ultimate independence [this is self-ironic; I understand that all kinds of clothes is communication etc]
