what kind are you getting? The plastic ones that fit into shoes, or the ones with the metal braces that are permanently fitted into a shoe?
This is the one I have. This is a couple of shoes ago. I haven't worn it for the better part of a year. I probably need to, but I had some edema, and it's a little tight around the calf. And I've been feeling that I wanted to try to build up muscle in that leg. So, I've only worn it intermittently over the past year.
