I think there are some saddles that cause sit bone pain for a while until you get used to them. Someone wrote about one fairly recently, I think. So it would help to know which saddle Awsmile is using. Also it's important to confirm it's definitely sit bone pain rather than pain on the narrow bones in front of them -- that would indicate a problem with fit or saddle width.

I have also looked for shorts with less padding in front than under the sit bones. The only ones I found were the Gore Oxygen and Xenon. But the difference in thickness between front and back is not that much.
