So everything I have read talks about the need for walking poles, so some good ones happen to be on sale at Sail and I picked them up. These are telescopic pole with wrist straps and interchangeable feet, so the question is why do I need them I can walk (most of the time). They say it is for up and down hils but that means I am going to be carrying them the rest of the way. Or do I use them the whole time? I guess some actual training will have to happen with the poles.
