Special Design: Designed for high insteps. The instep and length shoe stretcher turns any shoe into a perfectly fitting, comfortable shoe. It saves you weeks of wearing new shoes. With the shoe stretcher, your shoes can be stretched in length and height. .Premium Quality: Made of polyurethane plastic and stainless steel. Stronger and more durable than ordinary wooden shoe stretchers. In addition, it is antibacterial and effectively prevents odor. .Perfect Fit: It also comes with built-in small holes in the instep area. The plugs inserted into the small holes can stretch the shoes to the problem areas that are prone to pinching. Suitable for leather, suede and other natural materials. .Easy to Use: Follow the instructions below. You usually have to leave the shoe stretcher in for at least overnight, and sometimes even for 24-48 hours. The longer the shoes are in the stretcher, the more they are stretched, so you may want to try a shorter time first, because shoes that are too loose will not be comfortable to wear.
