In skiing the inside leg of the turn, the uphill leg at the end of the turn should always be more flex than the stance or outside leg. Bending the former outside leg makes it become the new inside leg. This bending is the action that starts the new turn. Flexing the long leg to make it become the short leg should not happen by luck or by happen stance. You can liberate action that you should practice and emphasize. We can learn and practice this on the slant board. To begin the exercise, lift your uphill leg by bending at the knee and hip, not by standing taller, and tip the foot toward the little toe edge as it would be in a ski turn. Next, flex the downhill leg, lowering the torso until the lifted leg touches the board. Keep the uphill leg flexed while this is done. You are trying to match the bend of the lifted leg by flexing the longer stance leg. After you have flexed the long leg enough to match the short leg and the uphill boot touches the board, tip both boots and legs to the downhill side of the slant board.
