driving barefoot is fine and safe solong as you do not mind risking getting athletes foot or other foot fungus from another driver. This is like using bowling shoes at the bowling alley without them spraying the shoes first. Sandals and othe loose footwear can cause dangerous situations as they are not securely attached to your feet. Sure they are no problem when everythig is fine but if an emergency situation pops up it can cause danger
