Cramer's 'Mad Money' Recap: Just Do It Like Nike

It is also important for companies to be able to expand internationally, not just among products, he continued. Cramer called Nike a "global brand" and said that Under Armour has made inroads in Europe and Asia.

Moreover, Under Armour had promising guidance and said it expects revenue to increase by 30%, he said. Plus, despite all the rumors, Cramer does not believe it will get taken over.

Under Armour, he said, "is the next Nike, or at least the next Reebok, which got taken out for twice what Under Armour is worth."

Crocs Comfort

Moving on to Crocs(CROX Quote), Cramer called it a great performer that he's proud to have caught a double in.

But although Crocs has had "stellar growth" and people love its product, "it is no Under Armour, which is why it's cheaper," he said.

Nike became a "powerhouse," and Under Armour could follow suit, because it has a brand that is extendable, Cramer explained. So, although Crocs is a great brand for shoes and sandals, Cramer believes it "would fail" at the apparel business.

"It is, in the end, just a shoe company," Cramer said. It could try to make it with international growth, but 30% of its sales are already from abroad, he said.

Cramer predicts that Crocs "will hit a wall and will probably never recover." He said it could be like Deckers (DECK Quote), the maker of Uggs.
