As a product expert, it's important to note that these boots come in women's sizes. The Pisa material is a medium-weight milled nappa leather with a super-soft tumbled texture and a richly pigmented waxy finish. To keep them in top condition, simply wipe away any dirt with a damp cloth and use a neutral or color-correct wax based shoe polish. For extra shine, buff with a Dr. Martens Shoe Brush.
