Grade: 3
Another calf strain, on R soleus, medial side. Took a tumble at trail run a few days earlier that may be triggered tightness. Chiro also found tight band on right soleus, so possibly also compensation injury.
Changed shoes and voila... it took me 5 months to realise the injuries and the introduction of new shoes 1 month apart were related. Changing away from Sense Pro to Sense Ride solved the problem within 2 weeks.
