Right now I'm looking at the Adizero Mana 5, Saucony Kinvara,Brooks t6 racer, and Karhu the racer (these are the ones that were in my price range and in stock in my size at runningwarehouse.) I'm looking for a shoe that I can wear for 5 and 10k road races as well as some tempo runs and faster training. I want something lightweight but still durable as I dont want to be replacing it after 60 miles. I am a fairly nuetral runner and my normal training shoe is the Mizuno wave rider. All these shoes are in my price range (under $80) but i really am having trouble deciding which one i prefer... any thoughts?
