Using the test board is generally the best way of selecting classic and skating skis. This method is indispensable for choosing classic skis with a waxed base.
The advantage is that you can choose the ski that ideally matches the customer’s weight. You are then also able to see the length of the waxed zone and mark it on the ski.
With skating skis it is extremely important to find the ski with the right tension for the customer’s body weight.
