Fat feet?

Hello -- First-time post here. I've been searching for the elusive F-Type with manual. Finally found one a couple of weeks ago and drove six hours to see it. To my surprise, I found that my left foot brushed the clutch pedal between shifts unless I made a very conscious effort to keep it from happening. Granted I have largish feet -- 12-13M, big but not wide. Has anybody else had this experience? Is anyone aware of narrower aftermarket pedals that can be swapped in to eliminate this issue? Thanks for any help/advice.
