Nike's (NKE - Get Report) investors may like NBA star Kevin Durant's ridiculous level of self-confidence. 

"As humbly as I can say it, I'm not an $88 player -- I'm an elite player in the league," said the newly minted Golden State Warriors forward Durant in a new interview with Nice Kicks.

Durant's Nike sneakers have skyrocketed in price from about $88 to more than $150 in recent years.

Durant added, "On these shoes, you get it all, and for a nice price -- you get the newest innovation, you get the newest Zoom bag, and you get my story along with it -- hopefully people understand, and I think a lot of people have."

The footwear and apparel giant is fresh off the introduction of the KD 9 -- Durant's signature basketball sneaker -- at the retail price of $150.

Past iterations of Durant's shoes have fetched about $200 upon their launch, as with the KD 8 EXT "Floral Finish" and Nike KD Elite "Black" that debuted in May.

The next two releases for the Durant line will be slightly more affordable than that. The Nike KD 9 "USA" -- decked out in red, white and blue for the summer Olympics -- and KD 9 "Mic Drop" are hitting stores in July at $150, according to SneakerBarDetroit.com.

But sales trends for Nike's signature basketball sneakers suggest a lot of consumers no longer understand the absurdly high prices for sneakers hawked by stars such as Durant, LeBron James and Kobe Bryant.

Sales of Nike footwear in North America rose a paltry 2% year over year to $2.3 billion for the fourth fiscal quarter ended May 31, due largely to sluggish sales of basketball sneakers in the face of greater competition from Under Armour (UA - Get Report)  and Adidas (ADDYY) .

Nike's results marked a steep slowdown from the third quarter, when U.S. footwear sales rose 16%. For the fiscal year ended May 31, Nike's footwear sales increased 9%.

Nike CEO Mark Parker conceded to analysts there were areas the company didn't "execute as planned" during the year. One of those areas was basketball sneakers.

Meanwhile, sales of basketball sneakers at Foot Locker (FL - Get Report) fell by a mid-single-digit percentage during the first quarter. Despite strong interest in Under Armour's Stephen Curry basketball sneakers, Nike's LeBron James and Kevin Durant lines "proved the most challenging," said Foot Locker.

Foot Locker CEO Richard Johnson said the company was dealt a "body blow" in its signature basketball business to kick off the year. On the positive side, Nike's Jordan brand had "excellent results," said Johnson.

Durant may not be an $88 player, but consumers likely wouldn't mind paying a little bit less for his sneakers for a change.
