I've switched shoes several times in the past couple years, looking for that elusive "perfect" show for me (5'11, 148).
I'm embarrassed to say it, but the best racing shoes I've run in are Skechers Go Run 2. Fairly minimal, 4mm drop, and is easily the most comfortable shoe I've ever worn. It's not for the track, but on fast courses it's fantastic for me.
Any big favorites out there?
