FAQs

What is the primary benefit of the carbon flyplate?

The carbon flyplate is integrated into the midsole to provide enhanced propulsion and stability, helping to improve running efficiency on challenging trails.

How does the Vibram Litebase outsole contribute to performance?

The Vibram Litebase outsole is designed to offer superior grip and durability on various surfaces, while also reducing the overall weight of the shoe.

Is this shoe suitable for casual walking?

While comfortable, these trainers are optimized for performance trail running. For casual walking, you might find other footwear more suitable for everyday comfort.

How do I clean mud off the shoes?

Use a soft brush to remove dry mud, then a damp cloth for tougher stains. Avoid machine washing or harsh chemicals.

What does 'ACG' stand for?

ACG stands for All Conditions Gear, indicating that the product is designed to perform in a wide range of environmental conditions.

Can I use these trainers on the road?

These trainers are specifically designed for trail running. The aggressive tread and specialized cushioning might wear down quickly on pavement and offer less optimal performance compared to road running shoes.

What is the main advantage of ZoomX foam?

ZoomX foam provides excellent energy return and lightweight cushioning, which is crucial for maintaining comfort and performance over long distances.

Troubleshooting

Traction is reduced on wet surfaces.

Ensure the Vibram Litebase outsole is clean. For very slick conditions, proceed with caution and utilize trekking poles if available.

Shoe feels too firm after initial wear.

The ZoomX foam and carbon flyplate may require a short break-in period. Continue wearing for short runs to allow them to adapt to your foot.

Laces come undone during a run.

Ensure laces are tied securely using a double knot. Consider replacing laces with a more robust, trail-specific option if slippage persists.

Discomfort around the ankle.

Check lace tension, ensuring it's not too tight but provides a secure fit. The low padded collar is designed for flexibility, so ensure it's sitting comfortably.

Setup, Compatibility & Care Instructions

Compatibility: Designed specifically for trail running and ultramarathon activities on varied outdoor terrains. Not recommended for road running or indoor court use.

Care:

  1. Remove excess dirt and mud with a soft brush.
