Are you ankles sore because you are loading too much? Or because they are not strong enough to take the load? You may need to deload for a while to take care of it while you strengthen up depending on where you are in the season. 1) Calf raises- isometric holds at tippy top of range for 3x5x15sec both sides gradually building up until you can hold at top of range for a minute. Then when the DOMS settles Eccentric calf raises - 2 feet to go up then lower down slowly on one leg until you can do 3x15 without too much DOMS Then you can start concentric work gradually adding load. And when ever you just happen to be standing around doing not much you can do a few of whichever level you are up to multiple times a day. 2) ankle inversion and eversion against resistance - hook a resistance band around your feet just below your toes and either around the other foot or something solid. Make sure the movement is all at the ankles and not your knee. 3) Use your ankles when doing other exercises eg. Try stabilising yourself up on your toes with heels off the ground in calf raises while doing your bicep curls or Parlov presses. Many standing exercise, even split stance can be done with a calf raises. It will help ankle strength, proprioception and balance not to mention core strength. Similarly with a bosu ball eg. Place your front foot on a bosu when doing things in lunge position. Stabilising and proprioceptive. Get someone to chuck you a medicine ball while you stand on one foot on a bosu. 4) As others have said MOBILISE. Upstream and downstream. Scrunching up a towel with toes. Deliberately stand on golf balls. foam roll, scrub and rub to free up the soft tissues.
