The calf is super dense..old school,take a piece of wood(2x4 American) and do some up and down exercises w your heal touching the floor with the first inches of your foot and toes on the board. Do a set w feet straight, then w toes in and another w toes out.there are a bunch of YouTube videos for calf exercising. I had issues before and I found it was mostly cleat was a tiny,tiny bit too far forward. I am certainly not saying change your position..if you have no other problems or pain probably not advisable. The exercise and flexibility stuff is a non harmful place to start..some guys I know keep the chunk of wood under their desk and do tiny calf exercises during the day..
