My pair from 2011 Worlds lasted a year, used them both on and off the course, they eventually wore through the outsole (probably due more to the grit of local tees than anything else). My wife still has her pair, they are in excellent condition. They run 1/2 size small. The cheapest I've seen them are around $110.
