A herringbone is generally used on slopes that are too steep to diagonal stride up, but not steep enough to require a side step. This method is good on moderate slopes with softer snow, and involves walking up the slope with the skis in a ‘V’ with the tips pointing outward. The knees must be flexed and the weight must be placed over the knee as each step is taken. Rhythm in your stride will help a lot in the transfer of weight from one leg to the other. On steeper or icy snow, edging is vital, and is achieved by rolling your knees and ankles inwards on each step.
