I also wear a 14 in Nike running shoes and ended up with a 13 in last years rpd max. They fit great length wise and the bake really does get a custom fit around your foot. Side note on the bake, I had it done at total hockey in st peters and the kid doing it insisted I remain seated for the entire process. Against my better judgement I too his advice and ended up with a decent, but not great fit. Skated on them a couple of times and had some spots rubbing. I went back to total hockey and did the bake process again following the steps that alkali reccomends in there YouTube video and it's a game changer. Whatever size you end up with follow alkali's instructions for the bake. It does matter.
