So I have shit ankles. One was probably broken five years ago (black ice, came off bike, pretended it was sprained but tbh....) Walking over rough ground, slopes etc has been difficult. I got an ankle support for holiday last year. This year I thought I'd try walking poles. WOW! Really helped on the flat and going over rough ground it was a revelation. I felt so much more stable. Back in cottage and even the bad ankle is ok. Plus I was faster.
Really pleased I took the plunge!
