If I wear a size 43 in Diesel, what size would I wear in a Kurt Keiger shoe (men's)?

[elsizzle2000]

I live in the USA & would like to purchase a the Kurt Geiger KG Vernon shoes. I can only order them from the internet as there are no stores near me. So I want to make sure I get the properly fitting shoes in the first shot!

I am a size 43 (10 US) in Diesel shoes. What exact equivalent would I order from Kurt Geiger? I know the simple answer is a 43 but I need to know from someone who owns both Kurt Geiger & Diesel MEN'S shoes - if they run true to size or big or small? IE Diesel 43 = Kurt Geiger 44 etc.

I hope this makes sense - thanks!
