Terminology - Exterior part 2
The section located above the knee rolls is called the thigh rise. It is mainly used to increase coverage of the 5-hole.
The thicker portion on the outside of the leg pad is called the outer roll. It is included in the pad to prevent shots from being directed into the net should they slide on the pad surface.
The sliding surfaces of the pad are located on the inside of the leg pad. They allow the pads to slide on the ice. The surfaces also include protective padding for the knees and the calves of the goaltender.
