To clean your shoes, first remove any loose dirt with a soft brush. Then, wipe the upper and outsole with a damp cloth using a small amount of mild soap if necessary. Allow them to air dry completely at room temperature, away from direct heat.

A single New Balance Fresh Foam X Hierro v9 shoe (UK 10.5) weighs approximately 294 grams. This lightweight design helps reduce fatigue during long runs.

The Vibram Eco Step outsole features a revamped tread pattern with deeper 6mm Traction Lugs. This design provides superior multi-directional grip and traction, ensuring secure footing on a variety of challenging wet and dry trail surfaces.

The Toe Protect feature is an abrasion-resistant overlay positioned at the front of the shoe. Its purpose is to shield your toes from impacts with rocks, roots, and other debris commonly encountered on rugged trails, enhancing durability and safety.

Ensure you are wearing appropriate running socks to minimize friction. Check your lacing technique to avoid overly tight spots. Allow for a break-in period; the cushioning often adapts to your foot over the first few runs. If discomfort persists, reassess your fit or consult a running specialist.

Verify that the gusseted tongue is properly centered and flush against your foot, forming a seal. Ensure laces are tied securely but comfortably, as a loose fit can allow entry. Consider wearing trail gaiters for extremely rocky or sandy terrain.

While the Vibram Eco Step outsole provides excellent traction, no shoe offers universal grip on all surfaces. Clean the lugs thoroughly after each run to prevent mud or dirt buildup, which can reduce effectiveness. Adjust your running technique to be more cautious on exceptionally slick conditions.

The knit upper, while breathable, is not fully waterproof (unless it's a GORE-TEX variant). If the shoes get thoroughly soaked, the materials will absorb some water. Ensure proper air drying after wet runs, potentially stuffing with newspaper to absorb moisture and speed drying. Consider water-resistant socks for wet conditions.
