What's the big toe self check sheet?
This is a sheet to check the angle of deformity of the thumb. You can find out how severe your big toe is.
First, download the checklist and print it on A4 size paper. If possible, it would be perfect if you can print with the "fill all margins" setting. Now that you have created one for the right foot and one for the left foot, put your foot on it with the heel and the base of the thumb aligned with the red line, and check it on both the left and right foot.
