To use these shoes, simply slip them on and you're ready to go. The stretch-lace front makes it easy to adjust the fit. For safety, make sure the safety toe is in good condition before each use. When it comes to maintenance, clean the shoes regularly with a soft brush and mild soap. Let them air dry. Avoid exposing them to extreme heat or harsh chemicals. Also, check the outsole for wear and tear. If the slip-resistant feature seems to be reduced, it might be time to replace the shoes.
