Bouldering is a form of rock climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses. While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls. Unlike free solo climbing, which is also performed without ropes, bouldering problems (the sequence of moves that a climber performs to complete the climb) are usually less than 6 meters (20 ft.) tall. Traverses, which are a form of boulder problem, require the climber to climb horizontally from one end to another. Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings
Artificial climbing walls are used to simulate boulder problems in an indoor environment, usually at climbing gyms. These walls are constructed with wooden panels, polymer cement panels, concrete shells, or precast molds of actual rock walls. Holds, usually made of plastic, are then bolted onto the wall to create problems. The walls often feature steep overhanging surfaces which force the climber to employ highly technical movements while supporting much of their weight with their upper body strength.However, in more recent times, many problems set on flat walls now require the climber to execute a series of coordinated movements in order to complete the route. These routes were likely to have originated at the Stuntwerk gym in Germany, and the style of climbing can be said to closely resemble the sport of Parkour. The IFSC Climbing World Championships have noticeably included more of such problems in their competitions as of late.
