Please purchase without comments. Brand new, unused. Size M, which seems to be approximately 23cm to 23.5cm. The shoe is made by weaving rubber material and polyester tape into a mesh, giving it elasticity and a snug fit. The instep has a deep design, but the V-cut design is carefully crafted to look sleek. The heel uses soft polyester, making it less likely to cause blisters, and it's a two-way design that allows you to step on the heel. The shoe uses the brand's original "Pancake Cushion" insole, which was developed in-house. The high-density, low-rebound urethane cushion softens the impact when walking, providing comfortable wear. Since it doesn't use hard materials, it can be folded compactly and is convenient to carry. Another great feature is that both the insole and the main body can be washed with water (do not machine wash)!
