I've used these for about a month. There are no noticeable stains or scratches. These are used items, so please check the photos and refrain from purchasing if you are concerned. [Product Description] The recovery function remains the same, but the sole has evolved into a shark sole. While the sole thickness has also been upgraded, the design widens towards the bottom, enhancing stability. The upper design is both cute and stylish, making it a unisex and easy-to-use design. ■ Function Explanation [Walking on Clouds] By using a uniquely blended EVA material, we have achieved not only lightness but also a high level of cushioning and shock absorption. It fits gently against the bare foot and reduces the burden on the sole of the foot. [ARCH SUPPORT] By supporting the arch, it absorbs the impact at landing, reducing the burden on the ankle and knee joints, and the calf. [ROCKER BOTTOM] The rocker bottom allows for a natural forward weight transfer, supporting efficient and light walking with less energy. *Rocker bottom: The front and rear of the sandal sole are curved like a rocking chair. ▼ Insole [RECOVERSOFT] TELIC's uniquely developed "RECOVERSOFT" provides a gentle slope between the ball of the foot and the toes, exhibiting a finger-free function and supporting the toes in gripping the ground. A protruding front arch design is placed on the toe area to improve grip during stepping. In addition, by using a uniquely blended EVA, we have achieved not only lightness but also a high level of cushioning and shock absorption. It fits gently against the bare foot and reduces the burden on the sole of the foot. ■ Material: EVA ■ Features: ・Sole thickness: 5cm ・Sole surface specification: SILKY SOLE *SILKY SOLE: The T mark of the brand logo is concave, and the sole surface specification provides a smooth and comfortable feel on the soles of the feet.
