Yes, the FloatPro+™ midsole provides enduring cushion suitable for marathon distances. Their versatility also means they can handle road sections of a marathon route effectively.

A 6mm drop is a moderate drop, suitable for many runners. If you typically run in zero-drop or very low-drop shoes, you may need a transition period. If you experience discomfort in your calves or Achilles, it might indicate the drop is too high for your preference.

Yes, the ProMorph trainers feature a removable EVA foam footbed, allowing you to insert your custom orthotics for a personalized fit.

The primary advantage is its adaptable traction, meaning it is engineered to provide reliable grip on a wide variety of surfaces, including wet and dry roads, gravel, and light trails.

FloatPro+™ is designed for enduring cushion and durability, intended to maintain its performance characteristics over many miles of running.

Ensure the Vibram® outsole is clean of mud or debris. While designed for adaptive traction, extremely slick surfaces may still pose a challenge. Consider alternate footwear for exceptionally wet conditions.

If you are new to shoes with a heel-to-toe drop, gradually increase your mileage or transition slowly to avoid discomfort. Consider a professional fitting if persistent issues arise.

The FloatPro+™ midsole is designed for durability. If cushioning feels significantly reduced, ensure the removable EVA footbed is properly seated. If the midsole foam itself has compacted, consider replacement after extensive use.

Ensure the laces are adjusted correctly to allow for natural foot expansion during activity. Break in the shoes gradually. If the restriction persists, these may not be the ideal fit for your foot shape.
