Koolaburra by UGGMen's Burra Short Fashion Boot

What is the difference between the ugg classic and the ugg koolaburra?

Is a men’s 10 equal to a woman’s 11wide?

Is it true you don't wear socks wirh ugg boots? sounds odd but who am i.

Since I am 11.5 shoe should I go down to 11 in boot, keep the the 11.5 or go up to 12
