What are the different types of boot outsoles?
The outsole is that part of the boot that comes in direct contact with the ground. Depending upon the activity the boot is designed for, the tread pattern can range from very aggressive (with hard and sharp-edged cleats) to somewhat smooth (with shallow and wavy ridges), with just about everything in between. Most outsoles, however, can be classified in one of four categories: Vibram lugs, air bobs, shallow tread and hiking/athletic.
