Saucony's patented walking technology made of Hytrel, which provides essential heel cushioning, forefoot pressure dispersion and arch support. The visible ISD also works to provide torsional rigidity and shock absorption. Moulded triangular pillars in the midsole that work independently to absorb shock and disperse pressure. It is an excellent last for runners who are bio-mechanically efficient. This is the EVA insole of Saucony shoes and is generally removable for the provision of orthotics.
Ionic design is added to many sockliners for improved cushioning.
It also increases the size of the landing surface to further improve cushioning. Resilite is Saucony's exclusive polyurethane compound which offers lighter weight and greater resilience. Created specifically for women, this traditional women's last with the narrow fitting heel offers a more secure fit and a slimmer profile, without sacrificing a roomy toe box. A safety feature used to increase visibility. A rigid material built into the midsole to support the foot's arch.
