What did Brando buy with the 2,000 pesos he acquired and what does the purchase show about his character?

After Brando stole the Witch's 2,000 pesos from Luismi's pocket without Luismi's knowledge, he spent the money fairly soon. A few days after his deceptive act, he bought a pair of red and white Adidas that cost him nearly the entire sum. Brando felt absolutely no guilt or regret about his decision, even after it became clear that his theft had created a major rift between Luismi and the Witch.
