You could be dressed to kill if your riding boots do not sport a wedge heel. A moment of imbalance is all it takes for a foot to slide through the stirrup creating the potential for a nasty accident. Being dragged by the ankle rarely ends well for the rider. Wearing a boot with a low wedge heel and ankle support significantly reduces your chances of dangling upside down from an animal that flees danger first and asks questions later. Types of sole and tread also require consideration.
