I wish I had a shoe room but I only have about 5 pairs so would be a pointless idea. I do get what you mean about having run specific shoes e.g. you wouldn't go round running in spikes!?
I would say Inov-8 f-lite 230's even thought they are a dry trail shoe (shaved a minute off my 10k time with them) but it's down to personal preferance e.g. arch type, cushioning, whether you have a heel or midfoot strike and many other factors!!!
