The term 'CLIMBER'S NEED' is composed of two crossword solutions: CLEAT (5 letters) and TOEHOLD (7 letters). A CLEAT is a metal or plastic device with spikes that climbers attach to their shoes to help them grip the rock face. Toeholds are small indentations in the rock face that climbers use to support their feet while climbing. Both cleats and toeholds are essential for climbers as they provide stability and support while scaling a rock face.
