Karakal Performance Sports Trainers Shoe Insoles Shock Absorbent Gel Sole Our aim was to create an insole that was comfortable, practical and supportive. So with that in mind we have included impact zone pads at the heel and forefoot and Air Chambers in the heel and arch to provide exceptional comfort. The surface layer is made using sweat absorbent breathable mesh. This increases the foot�s ability to breathe whilst also providing excellent comfort.It is also fitted with Shock Absorbent Silicone Gel cushioning that helps with energy rebound and aids performance. They are also designed to give a prescriptive style of strong foot support with a stability control device that helps centre the foot and provide comfort and flexibility.
