1) why do you need a full race boot? LOTS more options, that are still VERY stiff, in a less narrow boot? True race boots, are VERY narrow, and VERY stiff, and usually only go up to a 28ish
2) where are you located, odds are we can suggest a store to help you with the search. Better to look for a good store, and odds are they will have the right product for you, then look for product, that an average store will not know what to do with, or even have in stock
3) if you are 14 shoe, you will NOT be a 14 in a ski boot. more like a 30 depending on brand and the fit you are looking for This will give you LOTs more options, well at least a few more/.
4) lots of things have changed in 20 years since you last where in the sport. Skis are shorter, wider, and have more shape. To work better with the new skis, boots are more upright, softer, (and warmer and lighter too)
