Got ankle mobility issues? Here's an excellent ankle exercise from youth conditioning expert Pat Rigby that you might want to put in your too box:

The ankle circle drill I’ve used to effectively warm-up and strengthen the lower leg musculature with many athletes is helpful in most cases. To perform the exercise, stand on both feet with the weight on theoutside of each heel. Slowly rock the bodyweight forward so that it is on the outside of the forefoot (the fifth or smallest toe). Continue by transferring weight to the medial aspects of the great toes, then backward to the medial aspect of the heel. From there, reverse the direction and rock to the medial aspect of the great toe, to the lateral aspect of the fifth toe, and posterior and lateral aspect of the heel. That is one repetition. You’ll want to perform 10 repetitions.
