And what type of shoes are they. I alternate Nike Elites and Mizuno Wave Elixirs, and they both start wearing down in the 300-400 range, though I usually wear em till about 500.
Also, how do people running 100+ mpw deal with the financial expense of replacing shoes every 4 to 5 weeks if you replace the shoes roughly every 500 miles? Seems like you could easily shell out 1000 bucks a year just on shoes.
