This is REALLY going to confuse the issue but I'm a 10 in everything and 9.5 in Adidas.
Suciu, AdiEase, Lucas, Stan Smith, Silas all 9.5
Only tts Adidas for me was the Buz vulc and Silas SLR. The rest I had to go half size down.
To SFB's point, he's right. Everyone's feet are shaped so differently. When it comes to Adidas I'd try them on before buying.
