These ASICS Gel-Resolution shoes are ready to wear right out of the box. They are designed specifically for tennis, making them compatible with various court surfaces (hard court, clay, grass) due to their versatile herringbone outsole, which is effective at preventing dirt accumulation. Care Instructions: 1. Cleaning: After use, gently wipe down the shoes with a damp cloth to remove dirt and sweat. For stubborn dirt, use a soft brush and mild soap. 2. Drying: Allow shoes to air dry naturally at room temperature. Avoid direct sunlight or artificial heat sources, as this can damage materials. 3. Storage: Store in a cool, dry place away from extreme temperatures. Using shoe trees can help maintain their shape. 4. Avoid Machine Washing: Do not machine wash or tumble dry, as this can degrade the shoe's structure, cushioning, and adhesive properties. 5. Insole Care: Removable insoles can be taken out and aired separately to prevent odor.
