The Ultra 100 GTX from DYNAFIT is designed for long-distance runners who are prepared for any weather. This waterproof trail running shoe offers exceptional performance in wet conditions, allowing you to push your limits without worrying about the weather.

The shoes are designed primarily for long-distance trail running and are ideal for athletes who need a lightweight, precise and high-performance shoe for their most demanding runs. Whether you're training or competing in ultra distances, the Ultra 100 GTX is designed to support your every step, even in challenging weather conditions.

The upper is made from a durable Gore -Tex Invisible Fit membrane , which provides complete waterproofing while maintaining breathability. This means your feet will stay dry and comfortable even during long runs in wet conditions. The seamless tongue construction reduces pressure points, providing extra comfort on long runs.

The midsole is made of a lightweight, responsive compound that provides excellent cushioning while being 20% lighter than traditional EVA midsoles. This provides a comfortable and energetic feel with every step, and provides excellent energy return for improved performance. The outsole features Vibram® Megagrip with a deep 4mm tread for exceptional grip and traction on rugged and slippery terrain. The curvature of the outsole helps create a dynamic and fluid transition for a smooth run.

The shoes feature a traditional lacing system that can be adjusted for a secure fit. An elastic lace guard keeps the laces in place and prevents them from getting caught during your run. The waterproof construction is reinforced with a protective layer that improves durability and protects against dirt. With a 6mm drop and maximum volume, the Ultra 100 GTX shoes provide a supportive and precise fit, making them a reliable companion for any trail run.
