New Balance FuelCell Propel v5 Running Trainers - Grey - Size UK 4

The FuelCell foam provides a highly responsive and propulsive feel, designed to return energy with each stride and help drive you forward.

The shoe features a structured upper for a lightweight fit. While it offers some flexibility, it's recommended to try them on or check specific width options if available, as it may not accommodate very wide feet comfortably without a break-in period.

The FuelCell midsole foam contains approximately 3% bio-based content, which is made from renewable resources to help reduce the product's carbon footprint.

These trainers are primarily designed for road running. While they may handle light, packed gravel, they are not recommended for technical trail running due to their outsole design and support structure.

The TPU plate is integrated into the midsole to further enhance the propulsive feeling and provide a more dynamic transition from heel to toe.

Keep the shoes clean by wiping them with a damp cloth. Ensure they are dry and stored properly. Avoid machine washing or extreme heat, which can damage the materials and affect performance.

Yes, the FuelCell Propel v5 series comes in various colorways and sizes. Please refer to the product listings for available options.

Wear the shoes with athletic socks for a few short periods to allow the structured upper to break in and conform to your foot shape.

Ensure the shoes are clean and free from debris, which can sometimes affect foam performance. Check for significant wear on the outsole and midsole.

Verify you have the correct size and fit. Consider if the level of cushioning meets your needs for extended distances; a more cushioned model might be preferable if discomfort persists.

Ensure laces are not overtightened. If the issue persists after break-in, consider if the shoe's structure is suitable for your foot type.
