Using these work boots is straightforward. Just lace them up tightly using the dual - purpose metal lace hooks to get a secure fit with the help of the KONNECTFIT heel - capture system. The boots are suitable for various work environments, especially those where kneeling is required thanks to the KEEN.BELLOWS FLEX technology. When it comes to electrical work, remember these boots are EH rated up to 18kV, so they'll protect you from accidental contact with live electrical circuits. For maintenance, clean the waterproof premium leather upper regularly with a damp cloth. If the boots get wet, let them dry naturally away from direct heat. Replace the removable footbed when it starts to lose its cushioning. And always check the outsole for wear and tear. If the non - marking rubber outsole shows excessive wear, it might be time to consider a new pair to maintain their slip - resistant properties.
