Liza Jane,
I am so sorry. I have these pole, mine are a different brand, but they are so valuable for any type of walking where you are on uneven ground. These are a great price. I remember mine were pricy. I've used them when we went camping and the campside was on the side of a hill with large rocks making up the pathways. By all means suggest the kids get you some. I just forgot about them until David mentioned them. We bought them pre-knee replacement and I used them a lot. Sorry I forgot. I'm digging mine out again. Thanks David.
