All good suggestions and thoughts. My boots are fine. I have a couple of different pair. I think shine hit it, I think it's probably more my back and the nerves involved. I will keep experimenting and see if I can relieve it. I usually have to take my feet out of the stirrups for a while and stretch out my legs. It's just really irritating because I love to ride.
How can I tell by looking if my stirrups are jointed? I am pretty sure they are (I remember buying them) but would like to double check.
