This thread is to get the sizing down for various shoe brands. I propose we use the Converse Chuck Taylor in US sizing as the gold standard and show all sizes from other brands in relation to it. The reasoning is that Chucks are easily obtainable and many people already have or know what their size is. I wear a size 9 in Chucks. I know for: Converse Jack Purcell: +0.5 (I wear a 9.5) CT: -1 (I wear an 8 US, 7.5UK) I am looking at COSTUME NATIONAL HOMME, anyone know if I should size up or down?
