Hi, I am also having trouble with sizing. I currently wear a 12.5/13 US shoe. My Bauer XR5s are an 11.5. Although I can fit (at least) a screwdriver blade down the back. Should I order 11s or 11.5s? and would the Shift or Max's be better for someone who is 200 lb? Sorry I realise its a hard to size without actually trying them on.
