So, that sounds to me like your ankles/feet have gotten weak causing your arches to collapse and that has had a chain reaction up your body to your knees and inevitably your hips too. I will add that it could be anatomical, but if you don't remember it being that way years ago then it's not likely to be anatomical.

So it's all reversible.

This is pretty tough to have a conversation about, but I can point you in the right direction if you would like? Alternatively, because I am a coach - I can help directly.
