Toe holds are a type of climbing technique used to ascend a rock face or other steep surface. They involve using the toes to create small indentations in the rock, which can then be used as footholds to help the climber move up the wall. Toe holds are an important part of rock climbing and can be used in combination with other techniques such as handholds and friction. The term 'toe holds' is derived from the four-letter word 'FEET'.
