pro tip - use the EU sizing instead of the US. I've noticed I get on the whole much better results. I also wear a "13" but I noticed that the "13" that fit me generally are 47.5. I've seen the following sizes for the US "13" 46, 47, 47.5, 48 ....so I generally do better when I select sizes by the EU ones.
