I wear Rain, Inca, Oscar and Soller. For narrower lasts like Acludia and Forest I size up half a size to 6.5UK. If I can get an extra wide forrest I stay with 6UK. All my shoes from Antonio are 6UK, either with a slightly modified last to accommodate my wide foot or perhaps just a standard wide last. If it helps I can try take a picture of one of my Carminas and Antonio's shoes side by side, but I am not sure it would show you much.
