This shoe size is based on leather shoe size selection. For example, if you wear size 36 in leather shoes, choose size 36 for this model. If you usually wear size 37 in sports shoes, choose size 36 for this model (except for wide feet, wide instep, and high instep). The round toe design is comfortable and elegant, preventing toe crowding and outward deviation. The soft sole and upper provide comfort during walking. The comfortable heel design helps to evenly distribute pressure and minimize foot fatigue. Grateful for parents in every step of life.
