Heel Clutching System is an external Pebax mold that 'clutches' the entire rearfoot. Replacing the shoe's internal heel counter, it works like an exoskeleton, providing support while drastically reducing the potential for irritation. Besides making the shoe lighter, Heel Clutching System creates a more customised fit for different foot types.
ASICS High Abrasion Resistance Rubber (AHAR) is a tough compund used at the heavy contact area of the outsole, for example the heel. It helps to reduce excessive wear.
