It depends on how heavy your pack is. You might want one for stream crosses. If you do decide to use them learn and teach ethics of not poking plants or widening trails and definitely use rubber boots on them which attach securely.
The bad behavior of not using rubber boots and poking banks unnecessarily is desetroying trail and biodiversity at an alarmying rate. We need this ethics of rubber boots and not poking moss or plants reinforced. Also learn about pass and stepping aside for groups that go first and do not trample vegatation. Do not be in a hurry when passing. It is not polite or good practice to quickly trample vegetation and think you are behaving well on trail.
