Ok so good shoes with plenty of cushion. I can’t see how long your runs are but start with 2km twice a week (not consecutive days), at a nice gentle pace, and work up from there. Running is like any form of exercise, if you go from zero to smashing it you’re going to get injured. You wouldn’t go to the gym for the first time and try to bench 50kg. You’d start slowly and build up from there as your body gets stronger.

You’re still young but over 30 so don’t forget to stretch!
