My last two runs have been in my brand new horribly expensive Nike Air Pegasus 27 shoes. However, they surpass awesomeness. So cushiony that they actually feel spring-y and they are really flexible too. I also order a half size up based on advice I read on running boards and I think that really does make a difference. Have new arch supports but haven't run with them yet as you're supposed to wear them a bit 'normally' before running in them.
