SPECIAL DESIGN: Designed for high instep feet. The instep and length shoe stretcher helps transform shoes into comfortable, well-fitting footwear. It reduces the time needed to break in new shoes. With a shoe stretcher, shoes can be adjusted both in length and height. PREMIUM QUALITY: Made from polyurethane plastic and stainless steel. Durable and more robust than traditional wooden shoe stretchers. Resistant to bacteria, helping to prevent odor. PERFECT FIT: Features built-in holes in the instep area. Included plugs can target tight spots where discomfort occurs. Effective on leather, suede, and other natural materials. EASY TO USE: Follow the included instructions. Typically, leave the stretcher in overnight or for 24-48 hours. Longer insertion time results in more stretching. Start with a shorter period to avoid over-stretching, as overly loose shoes may reduce comfort.
