These unique men's spiked rivets loafers are a great choice for spring and autumn. To use them, simply slip them on. When choosing a size, measure your feet from heel to toe and compare with the size guide. They fit true to size, so you can take your normal size. The shoes come with a massage feature that provides comfort during walking. For maintenance, keep them away from sharp objects to avoid scratching the PU upper, lining, and insole. Clean them with a soft cloth regularly. If they get wet, let them dry naturally away from direct heat.
