What placements are you using on your calf?
Have you slid the placements?
Email me [email protected] I have a placement for you to use. Can’t post the photo says its too large .

The issue with running is most likely that your heels are not kissing
the ground. When this happens the calf remains contracted the entire
time which causes the soreness.

B. Have you slid the pads to make sure they are on the target area?
That is the first place to start.
