The biggest threat to leather shoes is getting them wet and drying them repeatedly. When your shoes get wet, you should never accelerate the drying process and instead allow them to dry naturally. Never use hair dryers, shoe dryers or place on or next to a heat source. This will dry out the leather and leave it hard and brittle.
Instead, remove the insoles and place paper towels or newspaper inside and leave them in an open space at room temperature to dry. Once the shoes are dry, we recommend applying the appropriate moisturizer such as leather conditioner or leather dressing.

Foam Cleaner
Gentle foaming cleaner that cleans surface dirt on shoes
Directions: Shake well before using. Use a stiff brush to remove excess dirt. Pump foam directly onto affected area. Using a soft bristle brush, work the foam in a circular motion. Wipe clean using a microfiber towel or terry cloth. For suede, nubuck and other nappy leathers. Allow the surface to dry completely. Loosen and raise nap using a stiff suede brush.

Leather Dressing
Naturally protects and preserves leather. Repels moisture, resists stains and acids, prevents cracking, and lets leather breathe.
Directions: Have leather clean and dry. Rub in well. Apply regularly on footwear, especially at the seams and the welt. Dry at room temperature. Remove excess if any. Buff to a shine when preferred. Not recommended for use on Suede or nubuck leathers.
