In response to Gerald
The Newton Gravities can do Marathon and ultra distances and I wear them for everyday running (circa 12-15 miles). They cost approx £110 (but they are coming down in price) and you can buy them from triathlon shops and a few running shops.
I run on tip toes and have done all my life and most people take the mickey out of me... it is just how I run and I can't help it. I would not class myself as 'super fit' or elite, but I can do the distances and this shoe really helps me. I have suffered in the past from various things such as black toe, blisters on long runs and tendonitis. However, the Newtons suit my style and touchwood... I am injury free.
I am not sure if they are value for money if you are a heel striker, but if you do run midfoot, forefoot anyway then I cannot recommend them enough.
