Abstract: A climbing shoe with a tension support attached to the heel area and toe area of the sole to assist climbers in maintaining a curve shape in their foot. The tension support pulls on the heel area and toe area of the sole to assist the climber in maintaining the ideal curve shape to support their weight on small footholds. The tension support reduces the fatigue on the climber's foot and calf muscles. The curve shape of the foot with the toes pointing down is ideal when a climber must support his entire weight with his toes on small footholds. The tension support is made of an elastic material that can flex and allow the sole to flatten out on larger footholds.
