Has anyone run a Tough Mudder Barefoot? I'm running Tough Mudder PA April 29th. I haven't run with anything on my feet since VFF's Thanksgiving 2011. I'd imagine I'll need VFF's for the obstacles, ropes, cables, etc. I have run a few shorter mud runs in my previosly uninformed, often injured shod past and can remember using my feet alot to grip the obstacles. The possibility of having to wear shoes is the only part I'm not looking forward to.
