- More heel decoupling for smoother landings

Carbon rubber for better traction
The outsole unit uses the XT-900 compound, which is a material made from carbon rubber. It is the one responsible for providing traction over the roads.
Lightweight blown rubber for durability
The IBR+ or the Injection Blown Rubber is a liquid-molded material that is durable and consistent. It’s a lightweight layer in the outsole, which shields the unit from abrasion and wear. The soft material allows it to provide some additional cushioning.
The Saucony Cortana 4 makes ample use of the PowerGrid technology, a high-quality foam that offers 20% more cushioning than most midsole foam units on the market. The Grid design helps to balance the foot, spread pressure evenly, and maintain a soft underfoot feel.
Efficient shock absorption
The SRC Impact Zone and the Impact Interface are components in the midsole which isolates impact and shock when landing the foot on the ground. The former takes care of the entire length of the shoe while the latter works more for the heel.
A Medial Post adds some support to the midfoot area, keeping the foot more centered and in line for a much more efficient stride.
The Cortana 4’s breathable upper
The upper unit of the Saucony Cortana 4 gives well-ventilated coverage of the foot with the use of the Air Mesh fabric. It keeps the foot dry and cool, permitting long-term use for those who want to participate in lengthy athletic activities.
The HydraMAX Collar Lining is a soft and irritation-free fabric that holds the heel snugly in place while giving a next-to-skin comfort that’s capable of staving off moisture. It’s an inner sleeve that allows runners to wear the Cortana 4 without socks.
A supportive framework
The Flex Film Overlays are welded in the upper and they were meant to secure the foot of the wearer and prevent wobbliness in the middle section of the upper. The Sauc-Fit adds more security in the rear part of the arch, as well as the heel area.
The Comfortlite Sock Liner was molded to the outlines of the heel and arch, essentially cradling the foot and making sure that each section of the underfoot is supported.
