Saucony's  Tri-Flex layout

The Triumph ISO 3 uses the Tri-Flex layout. This design is characterized by huge flex grooves, which are also deeper in this version than the previous version for even more flexibility. The rubber between the grooves is slightly wider for enhanced ground contact.

Saucony Triumph ISO 3 forefoot

A combination of IBR+ and XT-900 rubber delivers a nice mix of traction and durability. The former is located in the forefoot to the midfoot while the latter is placed in the heel and the tips of the forefoot.

Bouncier rides in the new Triumph ISO 3 midsoles

A full-length EVERUN top sole, which is just beneath the sock liner and the midsole offers excellent spring and consistent cushioning. The EVERUN is also used in some Saucony running shoes like the Triumph ISO 5 and Omni 16.

Saucony Triumph ISO 3 midsole

The midsole’s main foam is the SSL EVA for adequate responsiveness and durability. Giving the Triumph ISO 3 a distinctly bouncier ride and more cushioning is an Everun heel insert that actually extends to the midfoot.

Enhanced adaptability and ventilation in the upper

Saucony welcomes the 3rd installment of the Triumph ISO with a new engineered mesh with enhanced adaptability and ventilation. The ISOfit tech or the plush and supportive inner sleeve hugs the foot in wraparound comfort.

Saucony tweaks the exterior panel by using just 2 bands instead of 3 for a more forgiving fit. The upper uses FlexFilm overlays for melded, lightweight support. Luxurious comfort continues with the plush tongue and ankle collar. The flat laces cinch the fit of this shoe.
