Are nike dunk sb low true to size?

I have found this nike dunk sb low, and I am wondering are there true to my size. I am size 9.5 (43 EU) and the pair I have found is size 10 (44 EU). I know it's a whole size up but I have heard that the tongue of these shoes is quite THICK. Also my feet are quite wide but regular dunks are fitting me good. What do you guys think?
