How to Use: Just put on the boots like you would any other pair. Lace them up using the dual - purpose metal lace hooks for a secure fit. If you need a more relaxed fit, remove the gray insert below the insole. Note: These boots are for electrical hazard protection, but always follow safety protocols in electrical areas. Avoid exposing the boots to extremely high heat for long periods even though the outsole is heat - resistant. Maintenance: Clean the boots regularly with a damp cloth. If they get wet, let them dry naturally away from direct heat. Treat the leather occasionally to keep it in good condition and maintain its waterproof and barnyard - resistant properties.
