Why people get mad when I don't wear socks?

I grew up in Bali because of my parents job and I arrived in Europe at the age of 18. In Bali I used to only wear flip flops and it was a shock to wear closed shoes here. I never got used to wearing socks so I dicided to not wear them anymore.

People hate that. Why?
