Size 44 fits the normal way, but this shoe is despite the words "extra width" clearly too tight. In size 45 or 46 he would fit securely in width, for I would have good 3cm by Front game. I once bought by Rieker years ago a pair of shoes in size 44 "extra wide". At that time, was put on and feel good. This shoe is not going unfortunately. The build quality is top, however.
