Specifications :

• PU Coated, Polishable Leather & Nylon UpperTo reduce the weight of the boot, we combine polishable, polyurethane coated leather with incredibly strong nylon.
  
  
• 100% waterproof and breathable, GORE-TEX liners ensure that no water gets in, while allowing sweat and moisture to get out.
  
  
•  Prevents loose laces from snagging or dragging. At the top of the boot's tongue is a stretch fabric pocket designed to tuck your lace ends into.
  
  
•  The Striker® Bolt outsole is slip-resistant and offers maximum surface contact while gripping on and off pavement.
