So, this past august, I ended up rolling my ankle on a camping trip. After a week of hobbling around and an opening day, i decided it was time to bitch out and go to the doctor, turns out I spiral fractured my fibula (opps!). One walking cast and these poles later, I was still putting in 15 mile days in the mountains, albeit a bit louder than normal due to the walking boot, but still getting it done. The poles are very stable, and hold my 170 pound 5'7 frame up well! Cheers!
