I used to have this same problem so I definitely understand! Toes pointed out a little bit are ok but when they are all out your knees can't come in proper contact with the saddle. For jumping your toes are suppost to point out a little more over the jump itself. A way I found to fix this is to grip the saddle slightly more with your knees and a little more calf. You don't want a crazy death grip but you don't want floppy legs either. Hope this helped!
