Hello! I have been very frustrated with my ankles. I am not sure if I am doing something wrong that is causing them to give out or if I just have really awful ankles. It obviously doesn't happen when I'm trail riding, but after 45 mins of trotting & cantering (I ride English), my ankles just give out. It's like they become paralyzed and I can't keep my heels down or anything. They just kind of go limp. Last time this happened, I lost my stirrup and my horse bolted, resulting in a fractured arm after being thrown into a fence :( It's just so frustrating and I don't know how to help it. My family says we do have not-so-great ankles, but I can't imagine it would cause this. Has this ever happened to anyone else? Here is a video of me riding...maybe someone can see if I'm doing something to cause this. BTW: My horse has been sold.
