Setup: Simply lace up your boots to achieve a snug fit. The fold-over tongue can be secured via its integrated strap, ensuring it stays in place for a consistent touch and feel. Adjust lacing tightness to your personal comfort and support preference. Compatibility: These boots are specifically designed for artificial turf (TF) surfaces. The aggressive rubber outsole pattern provides optimal grip and durability on synthetic grass fields. While they can be worn on other surfaces, performance and durability may be compromised. Care: To maintain the longevity and performance of your adidas Predator League Tongue TF boots: 1. After each use, wipe off dirt and debris with a damp cloth. Avoid harsh chemicals. 2. For stubborn dirt, use a soft brush and mild soap solution. 3. Do not machine wash or tumble dry. 4. Allow boots to air dry naturally, away from direct heat or sunlight. 5. Store in a cool, dry place. Info needed: [Specific recommendations for cleaning the HybridFeel upper material.]
