Brush dirt off your shoes with a shoe brush, brushing in one direction. Then wipe them clean with a soft cloth. A suede eraser is great for removing smudges or stains.
Keep your suede shoes away from water as much as possible. If they do get wet, let them dry at room temperature as direct heat can damage the upper.
Store your suede shoes at room temperature, away from direct sunlight. Between uses, slip a wooden shoe tree or scrunched-up paper inside your shoes to retain the shape and absorb moisture.
