Answer: 
Please see Spare Parts on how to order what you need. Walkstool is of so high quality that you normally should not have any problem with it. Our returns are nearly zero. When a customer or distributor contact us it's because a customer has lost a foot on the lower legs or have succeeded to bent a lower leg although it's made of aluminium. Even it the lower legs are very strong it can be bent if a big person is sitting on it in a steep hill and perhaps one leg take all the pressure. The same could be applied being out in very wet forest and one leg sinking down and the user doesn't notice that a foot has fallen off even though it's very hard attached to the lower leg.
