The Flux EVERYDAY+ sneakers are built for those who demand all-day comfort, durability, and a design that keeps up with their lifestyle. Whether navigating the city or stepping beyond, proper care ensures they remain in peak condition while adapting to your routine. Follow these steps to maintain their structure, performance, and unique character over time.

Storage

• Keep them in a dry, ventilated place to prevent moisture buildup and premature wear.
• Store them in a cloth bag or a cardboard box—never plastic—to allow airflow and help them retain their shape.
• Avoid direct sunlight and heat sources, as they can affect flexibility and cause fading.

Cleaning After Each Use

• Wipe off dust and dirt with a dry cloth or a soft brush at the end of each day.
• If they get wet, never use a dryer or direct heat. Remove the laces and let them dry in the shade in a well-ventilated area.
• Absorb liquids immediately with a dry cloth without rubbing. Let any remaining moisture evaporate naturally.

Pro Tip: If exposed to rain or dusty environments, allow the dirt to dry completely before gently brushing it off.

Material Care

• Use products specifically designed for textile and leather materials to maintain their structure and durability.
• Apply with a cloth in circular motions to ensure even distribution and absorption.
• Avoid applying excess product, as it may alter the texture or leave unwanted residue.

Deep Cleaning Without Damaging the Material

• For embedded dirt, use a specialized cleaner for textiles and leather to remove grime without affecting breathability.
• Avoid harsh chemicals such as solvents or strong detergents, which can weaken the material and compromise flexibility.
• Use a slightly damp cloth to remove residue while preserving the sneaker’s structure.

Keeping Them Comfortable

The Flux EVERYDAY+ sneakers are made to adapt to your foot over time, but here’s how to enhance the experience:

• If the material feels stiff, apply a small amount of textile or leather conditioner to the most flexible areas.
• For a more customized fit, wear thick socks during the first few wears to help mold them to your foot shape.
• Avoid forcing the shape with heat or water, as this can compromise the sneaker’s integrity.

What You Should Never Do

• Never put them in the washing machine or dryer.
• Do not use synthetic waxes or silicone-based products.
• Never let them dry in direct sunlight after getting wet.
• Avoid abrasive sponges or strong detergents.

Your Flux sneakers are made to move with you—through the city, your daily grind, and beyond. With the right care, they’ll stay with you every step of the way, evolving alongside your journey.
