Setup, Compatibility & Care
To ensure the longest lifespan for your New Balance NB FLASH trainers, start by adjusting the laces for a snug but comfortable fit across the midfoot. These trainers are standard UK children's sizing and are compatible with standard athletic or cotton socks. For care, it is recommended to remove surface dirt with a soft-bristled brush after use. If the shoes become damp, air-dry them away from direct heat sources to preserve the structural integrity of the materials. Avoid machine washing or drying, as this can break down the adhesives and padding.
