Mistborn #02 The Well of Ascension

What she really needed was a spikeway—a path marked by spikes driven in the ground that an Allomancer could push against, throwing themselves through the air again and again. On such an organized pathway, she'd once traveled from Luthadel to Fellise—an hour's carriage ride—in under ten minutes.
    But there was no spikeway from this village to Luthadel; there weren't even ones along the main canal routes. They were too hard to set up, too specific in their usefulness, to be worth the bother of running them long distances. . ..
    Vin turned, causing the skaa couple to jump. Perhaps they'd noticed the daggers in her belt, or perhaps it was the look in her eyes, but they no longer looked quite as friendly as they had before.
    "Is that a stable?" Vin said, nodding toward one of the dark buildings.
    "Yes," the man said hesitantly. "But we have no horses. Only a couple of goats and cows. Surely you don't want to—"
    "Horseshoes," Vin said.
    The man frowned.
    "I need horseshoes," Vin said. "A lot of them."
    "Follow me," the man said, responding to her Soothing. He led her out into the cold afternoon. Others followed behind them, and Vin noticed a couple of men casually carrying cudgels. Perhaps it wasn't just Elend's protection that had allowed these people to remain unmolested.
    The stocky man threw his weight against the stable door, pushing it to the side. He pointed to a barrel inside. "They were getting rusty anyway," he said.
    Vin walked up to the barrel and took out a horseshoe, testing its weight. Then she tossed it up in front of her and Pushed it with a solid flare of steel. It shot away, arcing far through the air until it splashed into a pool some hundred paces away.
    Perfect , she thought.
    The skaa men were staring. Vin reached into her pocket and pulled out one of her metal vials, downing its contents and restoring her pewter. She didn't have much of it left by pewter-dragging standards, but she had plenty of steel and iron. Both burned slowly. She could Push and Pull on metals for hours yet.
    "Prepare your village," she said, burning pewter, then counting out ten horseshoes. "Luthadel is besieged—it might have fallen already. If you get word that it has, I suggest you take your people and move to Terris. Follow the imperial canal directly to the north."
    "Who are you?" the man asked.
    "Nobody of consequence."
    He paused. "You're her , aren't you?"
    She didn't need to ask what he meant. She simply dropped a horseshoe to the ground behind her.
    "Yes," she said quietly, then Pushed off of the shoe.
    Immediately, she shot into the air at an angle. As she began to fall, she dropped another horseshoe. However, she waited until she was near the ground to Push against this one; she needed to keep herself going more forward than up.
    She'd done all this before. It wasn't that different from using coins to jump around. The trick was going to be to keep herself moving. As she Pushed against the second horseshoe—propelling herself into the snowy air again—she reached behind herself and Pulled hard on the first horseshoe.
    The horseshoe wasn't connected to anything, so it leaped into the air after her, crossing the distance through the sky as Vin dropped a third shoe to the ground. She let go of the first shoe, its momentum carrying it through the air above her head. It fell to the ground as she Pushed against the third shoe and Pulled on the second one, now far behind her.
    This is going to be tough , Vin thought, frowning with concentration as she passed over the first shoe and Pushed on it. However, she didn't get the angle right, and she fell too far before Pushing. The horseshoe shot out behind her, and didn't give her enough upward momentum to keep her in the air. She hit the ground hard, but immediately Pulled the shoe to herself and tried again.
    The first few tries were slow. The biggest problem was getting the angle down. She had to hit the shoe just right, giving it enough downward force to keep it in place on the ground, but enough forward motion to keep her moving in the right direction. She had to land often that first hour, going back to fetch horseshoes. However, she didn't have time for much experimentation, and her determination insisted that she get the process right.
    Eventually, she had three shoes working pretty well; it helped that the ground was wet, and that her weight pressed the horseshoes down in the mud, giving her a stronger anchor to use when Pushing herself forward. Soon she was
