One of the most important item a runner MUST have is an ice pack. We suggest having this version of the ice pack - An ice pouch. It is easy to carry, reusable and all it requires is ice to be filled in and voila you are ready. More importantly since it is a pouch, it can be twisted and adjusted to fit the contours of your body wherever is needed.
Eg Ankle, knee, bottom of foot, neck, shoulders etc.. having this ice pouch will give you all a much easier treatment.
