Has Anybody been to Kicking Boxing or Martial Art class

I ask because i have a kick boxing class and the reason why I even want to do it is because I saw from pictures everyone’s barefoot.
If anybody knows if they’ll suggest for me to take off my socks or every one just takes them off because of common sense or because they were asked or suggested by the instructor

 

I have kickboxing class every Friday night. I always wear wrestling shoes.

I've never seen a mop or cleaning supplies in the entire gym since June 2018.

It's safe to say that the floor is unsafe for my foot pores.
