You don't use your race as an occasion to test your running shoes.

  With these you do. Maybe do a 3 mile tune-up run to make sure there are not hot spots and it fits well, then you go race in it. Can't spend 50 miles breaking in a shoe with a life of 100 miles.

    I'd do something more like 13-15 miles.

    Maybe not a particular pair, but you have to have experience with any types of shoes. I would frequently buy two pairs, one I would normally train in and the other will be reserved for events. Even the pair reserved for event I would typically test run (hahaha!) at least once during training to spot any problems. Now, this is pure conjecture, I don't think the shoes magically make you more efficient. Efficiency is something you learn when running over long period of time. I would expect, to reap benefits of these shoes (assuming there are) you would need to get used to the new mechanics of running that the shoes will require.

      A carbon fiber spring isn't magic, it's mechanical engineering. Your foot has a natural spring built into it. This is just slightly more efficient.

  I could see using them in a couple of marathon-pace training runs, but definitely not the whole training
