Honestly, I do not usually buy Nike or Adidas shoes, but I have Nike golf shoes.
I buy Reebok shoes usually; my running shoes are 12
My biking shoes are 11.5 I think
My basketball shoes are 12
And my Nike golf shoes are 11.5
they are a little snug, but fit like an average 11.5


My Nike golf shoes are a 2001 model I think.
