Ever heard of those boots that can make you run faster? You can buy them with crowns in the Wizard City Commons where Zeke has them.
Take the Boots of the Slipstream for instance. You could go 4% faster than normal. That would've been good for the race in the Wizard101 Gathering 2009.
And the Boots of the Comet. An even faster one. But, also more expensive. For twice as much crowns it would cost, it goes twice as fast ( 8% ). Makes sense right?
