The Jock is highly freaked out by this, but not completely stupid, and so grabs his shoes and runs out into the mall, still wearing the enchanted socks. But being athletically trained, not to mention having size 20 monster feet for extra kick when sprinting, he quickly outdistanced the insane foot fetishist shoe clerk and got back to his car.
He realized quickly that his shoes wouldn't fit, but could still drive in socks, though it took some doing to manage the pedals with his new, much larger feet. He drove straight to Madame Loa's House of Voodoo, parking and running in to announce, "Someone put a curse on my feet."
The register clerk, a goth type, glanced at the jock's huge feet, raising his ringed eyebrows, while in the corner, Madame Loa looked up from her cards and simply looked amused. "Chil'" she said, "those be marvelous big feet, but that be no curse. That be jus' the way the Spirits made me."
"Oh yeah?" said the jock, shaking the size 10 1/2 shoes he had in his right hand. "Well this morning, the spirits had these shoes fitting me."
Madame Loa chuckled, then glanced at his feet and squinted. Then she raised her eyebrows. "Chil' come here...."
The jock did and she looked closer.
"Give me those socks," she instructed.
He peeled the socks off his enormous feet and she gestured to her card table where he then lay them. "This can be the work of only one t'ing," she pronounced gravely. "These socks been touched by the Amulet of Xandir."
"Amulet of What?" said both the jock and the goth.
"An anciente amulet," she intoned. "Some say it be made from the heart of a demon. Others, that it was the jewel fell down from Heaven an' made into the sigil of the Yellow Emperor of the Chinamen. All that's important though is that it enchants whatever bit of clothing it touches, only one at a time, and whoever be so foolish as to put that clothing on, it don't fit them, they fit it."
The goth asked, "So if I put those socks on right now, I'd get a pair of huge feet like that?"
Madame Loa nodded. "Same with anyone. Until the amulet touch another piece of clothing, then POOF! The enchantment on these ones vanish, an' it go to the new clothing. It touch a dress and you put it on, you become a woman!"
"Uh..." the jock asked, "will my feet go back to normal then, once he turns into a chick?"
Madame Loa shook her head. "No, they always be like that, not less you use the amulet again. You have it, boy?"
"I don't know what you're talking about."
She squinted at him, then sagged and sighed. "Someone be playing mischief with it then, touch it to those socks."
"What about my feet?" asked the jock.
Madame Loa mused. "Draw a card, chil'"
The Jock did, looking at a Tarot card of the Ace of Cups.
"That be the card of water," Madame Loa explained. "Great good fortune overflowing."
"The only thing overflowing are my feet," the jock said. "I'm going to trip over these things playing football."
"Any sport those good for?" asked the voodoo woman.
"Well," said the jock, "there's that Australian swimmer with the enormous feet... And mine are bigger than his...."
Madame Loa took the card and nodded. "If you go for swimming, you could go for the Olympics. Get very rich. An' famous."
"Wouldn't I need bigger hands too?"
"Magic's still on the socks, chil' Jus' you wait." She took out a pair of scissors, and like she was defusing a bomb, she carefully cut two holes in the socks. "Now they double as mittens."
The jock picked them up and tried them on, sticking his thumbs out the holes, and felt the tingling again as his hands got larger and larger and longer as well until at last they filled the sock-mittens, which he took off. He gasped. "They're as big as my feet!"
Madame Loa shrugged. "An' what do you care when you become a rich medalist?" She waved her hand at him dismissively. "Go, chil' Have a good life. Leave this magic business to those who know about it."
The jock nodded, frightened, and ran out of the store, while Madame Loa turned to the goth. "Well, Erebus," she said. "I t'ink we got an amulet to find...."
