Task: Wrong Candidate Generation
Input (English): Context: Ask anyone that knows anything about that line , even NB store clerks , and they 'll willingly tell you NB screwed up a great shoe . It simply was worse in many ways . And so I migrated to the pricey NB 1222 and then the 1223 ... while there was significant comfort , it was anything but comfortable paying for a pair ... and so I began looking around again . Good ol' discount shoe warehouses ... I found one delightfully comfortable ( in fit and price ) in the NB 645 , which is a nice wide - base shoe that fit the bill . 
Question: What may be the reason why I found the NB 645 ? 
Correct Answer: The NB line became pricey and worse in many ways.
Output (English): The NB line became delightfully more comfortable.
