Inverse Kinematics error in Motion

[Jobin Geevarghese ThampI]

Hi, as you can see this is snap of the model which i got while performing inverse kinematics. If you carefully observe the pic, the right foot of the model looks weird. Can anyone help me out why it looks like this?.

Hi,

Are the marker weights for the markers on the right foot much less than the other markers in your model? Also, if you scaled the model, that could be a potential source of the issue if it wasn't properly scaled making it difficult for IK to match your experimental kinematics. I hope this helps!

Kind regards,
Luke

But every marker weights were given as 1
Also, I got a new error this time and I have attached the screenshot here!...please help me out.
