I bought these trekking poles for my hiking trip to Colorado. Boy, am I glad I did. I hiked on some strenuous trails in Rocky Mountain National Park after the flood damage, which caused a lot of trails to become rocky and unstable. These poles kept my stability and took a lot of pressure off of my legs and my knees. They are very lightweight and easy to adjust. I love them and will use them on all of my hikes from now on.
