  • The Xodus ISO is a shoe that’s made to conquer the many types of terrain, while also making sure to keep the foot comfortable and secure. Resilient cushioning and dependable traction are given by this shoe’s internal and external sole unit. The upper is even very comfortable, hugging the foot in a snug manner that’s almost as if the runner is already wearing a sock.
  • The sock-like fit allows the runner to wear this running shoe even without using actual socks. The material used here is soft, flexible and non-irritating to the skin. Breathable coverage is only one part of this section’s purpose, because the interior lining is able to wick off moisture with ease. Runners are given a dry and cool interior, which helps them in getting a very comfortable running experience.
  • The mid-sole utilizes a high quality foam unit that’s meant to cushion the foot well, provide support and reduce impact pressure during the landing phase. This full-length material is springy and responsive, and it doesn’t break down easily, thus making the platform as efficient as when it was first purchased.
  • A sticky rubber compound is used in the outsole unit. Its job is to hold onto different types of topography, while preventing slippage or questionable surface control. Hexagonal patterns make upward and downward treks much easier. The rubber is also durable, thus it is able to shield the rest of the sole unit from wear and tear.

The Saucony Xodus ISO is true to its size. The sizes that are available for this shoe follow the standard measurements for men and women. The heel, mid-foot and forefoot areas have medium widths, so it’s able to let the runners with medium sized feet to ease well into it when wearing it. It has a natural semi-curved shape.


The Saucony Xodus ISO features the PWRTRAC, a highly durable rubber compound that’s responsible for shielding the sole unit from the abrasive nature of the trails. It doesn’t peel off easily, so it stays efficient at its purpose, even after the shoe has been used many times. This outsole material is also used in the Xodus ISO 3.

A hexagonal pattern allows the outsole to hold onto a variety of surfaces. Whether it’s technical ground, soft paths, uphill routes, or downward trails; this rubber unit is going to hold onto them with ease.


The EVERUN is a foam unit that’s durable yet responsive. It cushions the foot during impact, but also disperses the pressure gotten from the act. It is also able to assist the forefoot in lifting in a more efficient manner, because it has energy-returning properties. It is cushioning that’s placed really close to the underfoot for more comfort.

The ComfortLite Sock Liner is a molded add-on placed above the main cushioning system. It supports the contours of the heel and arch, while also getting rid of blister-causing pressure in the forefoot area.


The ISOFIT is a mesh material that’s stretchable. It adapts to the shape, size and natural movement of the wearer’s foot, thus keeping the experience as freeing as possible. It doesn’t irritate the skin, and it even feels like a sock when the foot is inside it.

The RUNDRY collar lining secures the rear of the foot responsibly. It has moisture-managing properties, so it keeps the foot dry at all times.

The Gusseted Tongue shields the shoe from any incoming debris. An interior chamber that’s free from debris makes the running experience more agreeable and comfortable.

A Molded Toe Shell guards the forefoot section from potential harm due to bumps and contact with debris.
