Good to know

  • The Saucony Triumph ISO 4 is a running shoe that’s created for the neutral pronator. It features an updated design that moves away from the layered look of its predecessor, the Triumph ISO 3. Instead of using separate layers of overlays, this one has the printed variety. It’s directly fused with the cloth-like mesh upper, giving a smooth and seamless façade.
  • The midsole unit makes use of the EVERUN, a foam compound that aims to provide cushioning and shock attenuation. A Topsole that’s created from the same technology has the purpose of gracing the runner with a soft underfoot experience. Rubber compounds shield the sole unit from the abrasive nature of the asphalt.

The Saucony Triumph ISO 4 has a standard running shoe length. It comes in sizes that follow the preferences of consumers. For the men’s version, the available widths are D – Medium and 2E – Wide; for the women’s version, it’s B – Medium and D – Wide. Other wide running shoes are also offered by Saucony. The semi-curved shape of this product mimics the curve of the human foot.

XT-900 is made from carbon rubber. It’s created to provide responsible traction over the surfaces. It’s also made to last long because it acts as a shield against wear and tear. It’s placed throughout the length of the s Saucony Triumph ISO 4.

IBR+ or Injection Blown Rubber is a lightweight compound that’s added to the forefoot section. Its responsive nature allows it to give additional cushioning and springiness to each step. It’s flexible, as well.

The Tri-Flex design is a network of grooves and patterns on the outsole that permits the flexibility of the wearer’s foot.

EVERUN is a foam unit that runs the entire length of the Saucony Triumph ISO 4. It carries the foot throughout the running session, cushioning it with every step. It also aims to absorb impact shock and disperse the resulting energy, potentially maintaining comfort as the runner goes through the gait cycle. This midsole foam is also utilized in the Triumph ISO 5.

An EVERUN Topsole is placed right above the foam that is more substantial in thickness. Its purpose is to immediately cushion the underfoot, supporting it and energizing each step.

The High Elasticity Sockliner provides a little more cushioning and flexibility. It has tiny pores that allow air to circulate in the foot-chamber.

Engineered Mesh has the properties of woven cloth. It wraps around the foot like a sock, preventing or reducing irritation in the process. It has ventilation apertures that allow air into the foot-chamber to keep the wearer cool and dry when running.

ISOFIT is a system that uses stretchable mesh and thin synthetic overlays. They’re patterned across the midfoot and heel sections, with the goal of providing a snug and secure fit. They connect directly to the lacing system, so they adjust in conjunction with the tightening or loosening of the shoelaces.

The RUNDRY Collar Lining is made up of fabric that hugs the heel and ankles. It’s formed to have a soft and smooth disposition. It has a moisture wicking capacity that prevents odor and the buildup of bacteria.

The padded tongue and collar hold the foot in place and prevent it from wobbling inside the Saucony Triumph ISO 4 during the run. They also prevent unintentional shoe-removals.
