Explore our selection of New Balance Fuelcell Summit Unknown shoes

For solid trail runs across varied terrain, the New Balance Fuelcell Summit Unknown running shoes are an excellent choice. We offer various models such as the V3 and V4, available in both men's and women's versions. Each model has unique features tailored to specific preferences and conditions. The V4 has been further refined with additional grip zones on the outsole for improved traction. The V3 feels slightly lighter and offers a slightly lower entry. Both models are ideal for neutral runners who like to combine speed with control during trail running.

Thanks to the wide range, it's easy to choose the model that suits your running style, distance, or terrain. Are you looking for a responsive, well-cushioned, and lightweight trail running shoe? Then the Fuelcell Summit Unknown is definitely the right choice.

Technologies for grip and comfort on trails

The shoes are equipped with the FuelCell midsole, a lightweight and energetic foam that provides extra bounce with every step. This makes the Summit Unknown highly suitable for those who want a powerful start or tackle hilly paths that demand strength. For solid protection on rough surfaces, the Rock Stop Plate is placed under the forefoot. It shields your feet from stones and sharp rocks without sacrificing flexibility.

The Hydrohesion outsole elements ensure strong grip on both wet and dry surfaces. This outsole technology is specially developed for trail runners who often face changing weather conditions. The sturdy outsole construction is durable, offers excellent traction, and prevents slipping. The seamless construction around the forefoot also adds comfort and prevents irritation during long runs.

Lightweight fit and practical comfort

The New Balance Fuelcell Summit Unknown is suitable for neutral runners and fits well with a standard foot width. Thanks to the breathable upper made of lightweight mesh, your foot stays cool even during intense trail runs. The lacing system ensures a secure fit that stays in place even on descents. With an average weight of around 280 grams (men's size 42), it is one of the lighter trail models in this category.

The shoes have a 6 mm drop, which promotes a natural foot position and responsive toe-off. This makes them ideal for runners who seek speed and precision on technical terrain. A reinforced heel counter provides extra support during lateral movements and keeps your foot stable in the shoe.

Built for performance in trail conditions

Trail runners choose the Fuelcell Summit Unknown for three clear reasons: grip, protection, and agility. The outsole features multidirectional lugs for extra traction on mud, gravel, and tree roots. Every step feels secure, even on wet ground or steep inclines.

The shoe also provides protection from obstacles without compromising flexibility or speed. The upper is rugged yet lightweight, and resistant to rain and mud. Thanks to the smart placement of reinforcements, the shoe maintains its shape well, no matter how intensively you use it. This makes it a reliable partner for both short explosive runs and long trail days.
