No, it’s not ‘shopped.
From what I’ve been able to gather, Einstein didn’t value clothing norms; he instead wore what felt comfortable. It’s well known that he hated wearing socks and had foot problems. It could be that he simply felt that these shoes were comfortable and really didn’t give a damn if convention held that supposedly only women could wear this particular type of shoe.
What are your thoughts?
Speaking as a woman…
I doubt he wore women’s shoes for comfort. Women’s shoes are generally less about comfort than men’s are. Our shoes are narrower throughout.
Maybe he just liked the way they looked. That’s cool.
