My wife opened the package and tried to put it in her shoes, but it was too big and she couldn't use it. If you don't have a large heel, men might be able to use it. There is no box due to shipping costs. Size: D (25.0-27.0cm) This is a functional insole for women's formal shoes, based on traditional biomechanics concepts. It alleviates heel pain and foot fatigue. The micro-suede top sheet provides a more comfortable fit. Applicable for women's flat heels and shoes with heels 2.5cm or less.
