The concern Deckers (NASDAQ:DECK) was showing that its UGG boots may lose some of their fashionable luster this season was overly pessimistic, it turns out, judging by the company's third-quarter results.

I shared those very concerns. I recently removed Deckers as an "outperform" pick in my Motley Fool CAPS portfolio and can only wish I had actually bought the shares when I first tagged it as an outperform!. But could it be that UGGs are here to stay for a while yet?

Deckers' third-quarter results insinuate that may be the case. Net income skyrocketed 86% to $19.3 million, or $1.47 per share. Sales increased by 57.2% to $129.4 million as well.

Of course, UGGs were a significant contributor, with a 67.5% increase in sales. In the company's press release, company head Angel Martinez touted strong full-priced selling of UGGs in the U.S. as well as a growing hankering for the brand internationally. Deckers' Teva sandals have lagged recently, but those sales improved, too, increasing by 12.1%. Customers appear to be responding favorably to the company's new closed-toe Tevas as well.

In more good news, Deckers has upped its guidance for the fourth quarter as well, anticipating 35% revenue growth and 15% EPS growth.

I recently opined on how it might be risky to invest in shoe companies, where faddish fashions may mask themselves as sustainable advantage and consumers can be notoriously fickle. I know many people don't agree with my suspicion that Crocs' (NASDAQ:CROX) wild popularity may turn out to be a fad, but Heelys' (NASDAQ:HLYS) recent crash should serve as ample reminder of what happens when growth abruptly slows. Timberland (NYSE:TBL) may have perfectly serviceable and practical boots, but it's hit hard times, and Skechers (NYSE:SKX) hit the skids recently, although it looks like it's regaining its footing.

It's terribly difficult to call fashion and consumer preference, and it's understandable that many investors have been nervous about Deckers' future, given its growing stock price and what looked like increasingly high multiples. And there's risk in the fact that UGGs has been the major driver, with Teva lagging and Simple still an infant brand. With more than a 27% pop today, I have to admit I'm still way too conservative (or nervous) to consider Deckers a good buy. Still, I salute those who hung tight. So far, Deckers has kept on delivering the growth.
