A.) I had an "off" day because normally I don't have issues (or very few) concerning slipping up like that.
B.) My stirrups are too short (I've had a few people comment that my stirrups should go up a couple notches).
C.) I'm just still a beginner that has a ton to learn.
Picture to see where my stirrups are-
Now my instructor always has me keep my stirrups down to that length so part of me thinks that where my stirrups are shouldn't be the issue and it's caused by rider fault.
Also, when my feet slip up are when:
A.) I have to "kick" my stubborn mount to have her go
B.) corners during the canter (like when I have to keep her pressed up to the canter)
C.) (yesterday was the FIRST time this slip up happened) I slipped up during the few strides between jumps. As in, I hopped over a cross rail and had a few strides between the next jump and my feet slipped up.
Again, I'm sure this is rider error--so I'm looking for some advice to fix this. I will be talking about this with my instructor this upcoming Tuesday so I can address it as soon as possible but in the meanwhile, I figured I'd at least get some advice so I can have an idea of what I need to do.
