Running shoe anxiety

I have 5 days until my next race and I'm beginning to worry about my shoes. I mentioned yesterday that I've had some issues with my feet that seem to relate to my Nikes. This morning I switched to my New Balance trail shoes for the elliptical and they were much more comfortable. I really don't want to race with trail shoes on pavement but I also don't want to continue pushing my luck with the Turbulence 13's.

I have a busy schedule at work this week so it will not be that easy to get to a store at lunch to look at new running shoes. I want to avoid buying a pair in haste without considering other options just because of Saturday's race deadline. I have been reading reviews and talking to friends and I'm thinking this is the time to invest in a higher end pair. AG told me about a few stores in the city that have treadmills so staff can watch you as you run and help recommend the best shoe choices for your running style. If I'm looking to pay a lot for a pair of running shoes I don't want to buy the wrong thing and be disappointed.

I've looked at the removable soles in my Nikes and, while they look okay, I have no idea how much cushioning and flexibility they've lost in the eight months that I've had them. I'm thinking about trying a pair of cushioned replacement soles to get me through the race on Saturday. If they do the job, great. If not I'll be paying a visit to a running store on Sunday.
