To use these Merrell men's Moab Speed 2 hiking shoes, just put them on like you would any regular shoes before you head out on a hike. Make sure the laces are tightened properly to give you good support. When hiking, these shoes will handle different terrains well. As for maintenance, after each use, clean off any dirt or mud with a soft brush and a bit of mild soap. Let them dry naturally, away from direct heat. Avoid wearing them in extremely harsh conditions that could cause excessive wear and tear. Also, check the soles regularly for any signs of damage. If the laces get frayed, replace them to keep your shoes in top shape.
