Gel cushioning is a **specialized shock-absorbing material** embedded in the midsole of many running shoes, often in the heel and sometimes the forefoot. It was originally inspired by medical-grade silicone gels designed to protect sensitive tissues, then adapted to reduce impact forces on runners’ joints. Unlike regular foam alone, gel systems disperse vertical impact forces sideways, spreading pressure over a wider area.
This can translate into softer landings, smoother transitions, and less stress on knees, hips, and ankles during longer runs. Modern advances such as **PureGEL** make these systems even softer and slightly more energy-returning than older versions. For endurance runners, this technology can support comfort and consistency across high-mileage weeks.
