foams.

Foam is a general term for the materials used in the midsole of a running shoe. Different types of materials are developed to meet different needs, and recent years have seen enormous progress in this area.

The optimal combination is a lightweight material that provides plenty of cushioning and high responsiveness (energy return). Add good durability and you have the perfect foam. This is what every material manufacturer strives for. In most cases, however, it comes down to a compromise, with more or less of each characteristic.

Generally speaking, foams used in fast racing and interval shoes are made from lightweight materials that deliver high responsiveness but lower durability. Shoes designed for daily mileage typically use foams that offer good cushioning and high durability, but lower responsiveness and greater weight.

Responsive cushioning (energy return) describes how quickly a material returns to its original shape. Think of a bouncing ball and how high and quickly it rebounds after hitting the ground. High responsiveness contributes to a more efficient running stride at the expense of durability and is generally best suited to road running and racing.

Px Foam™

An extremely lightweight foam that provides optimal responsiveness and excellent flexibility. This innovative material has a low density and is 20% lighter than traditional EVA. A perfect choice for intense running over extended periods.

Ud Foam™

A lightweight and durable foam that provides efficient propulsion for high-paced ultra-distance running. This EVA-based material features a unique chemical compound that delivers ultra-responsive cushioning and excellent durability. Speed and low weight are the key characteristics of this high-quality material.

Cr Foam™

Cr Foam™ is an ultra-lightweight foam with responsive cushioning that provides a soft and smooth running experience across most types of terrain. The material is produced using a process in which its different components are integrated under high temperature and pressure, enhancing its properties and helping improve running performance.

Ud Pro Foam™

An ultra-lightweight foam that delivers exceptional propulsion and helps competitive ultra-distance runners achieve maximum efficiency. A Pro version of Ud Foam™, this EVA-based foam features a unique chemical compound for superior responsiveness and minimal weight. Developed for running at the highest level.

Ar Foam™

A highly versatile all-round material that provides effective responsiveness, good stability and a smooth running stride. This EVA-based foam features a unique chemical compound that delivers an ideal combination of soft cushioning on landing and rapid acceleration at toe-off. Stability and a smooth ride are the key characteristics of this versatile material.

For all surfaces

Road-to-Trail

If you vary your running routes and run about as often on road as on gravel and forest paths, these hybrid shoes make a very good choice.
