CARE GUIDELINES

Protect your footwear to protect yourself.

  • Clean your shoes regularly.
  • Paying attention to your shoes in this manner will help you take notice of any damage
  • Remove excess dirt and mud by wiping clean with a damp (NB: damp, not wet) cloth.
  • Dry with a separate, dry cloth, and then leave to dry overnight at room temperature.
  • Do NOT force dry with direct heat as this can distort the leather and/or PU and cause it to crack.
  • Try to avoid scuffing the upper leather or treading on sharp edges or objects that may cut or tear the sole.
  •  Avoid using harsh chemicals on the footwear as this may cause the materials to breakdown.
  • For footwear which has a leather upper, regularly apply a good quality wax polish or shoe cream to extend its life.
  • For footwear which has a Nubuck or suede upper, rub gently with a stiff bristled brush.
  • Soles should be checked regularly and stones and metal shavings removed from the cleats.
  • Check the uppers and soles of your shoes regularly for damage. Worn out shoes will not provide the necessary safety and need to be replaced.
  • Pay attention to the laces. If they become worn, replace immediately. Safety footwear requires a good fit, which depends on the laces being in good condition
