Except for a short time following the apparition of the shoe craze, I was only required to take off my shoes when flying to the US. Even in airport that practice systematic groping.
Same is true for Brazil, Argentina (where I asked about liquid restriction to get back to Europe, and was told I could take liquid, "only the US makes us check for liquids", so it's widely believed...).
I have different experience with frequent travel through/to Brazil. I find that they fairly strictly enforce US-like liquids policies even when flying to countries other than the US.
