These men's casual sneakers are really easy to use. Just measure your feet carefully according to the size guide and pick the right size. Then, simply lace them up and you're good to go! They're great for daily wear in spring and autumn. When it comes to maintenance, you can gently clean the mesh upper with a soft brush and mild soap. Let them air - dry naturally, and avoid direct sunlight. The shoes are made to be durable, but try not to wear them in extremely harsh conditions. Keep them in a cool and dry place when not in use to maintain their quality. And don't worry about odors thanks to the anti - odor feature, but if you want to keep them extra fresh, you can use some shoe deodorizer occasionally.
