This woman is smart to ride barefoot. Shoes only get in your way on inverted rides like this. I of course did the same for this ride as well as all the others at Extreme World including the drop into the net.
This woman is also very clever to roll up her pant legs to just below the knee. By leaving the shins and lower legs bare it reduces drag. It was also clever of her to lock and cross her ankles on the ride which reduces drag. She must have planned this all out before going on the ride.
