A ski boot for lessening the incidence of knee injuries when the boot exerts a forward directional force on the skier's leg and includes a foot portion and a leg element. The foot portion and the leg element are in a first essentially rigid support position for the foot and lower leg for normal operative skiing position. Releasing means changes the rigid support position for the foot and the lower leg on application of a predetermined level of force by the boot on the wearer. Movement of one element of the leg portion permits the lower leg and foot of the wearer to adopt a second position different to the relative fixed location for normal skiing.
