These are unda geta (Japanese sandals). I've worn them about three times, but unfortunately, they don't fit my feet, so I'm reluctantly selling them. They look stylish even when worn with socks, so they should be great for winter. The following is quoted from the official website: "Two-stone thong" seen in traditional geta. Inspired by the design where two thongs are arranged in parallel, it has been updated for the modern era. "unda DUAL" is a pair characterized by a double-structured thong and a three-dimensional sole design. What catches the eye is the double-structured thong that combines different materials. Soft PU suede is used on the inside, not only to enhance the design but also to pursue a secure hold and comfortable fit for the foot. The stable comfort supported by the two thongs brings a new sensation that has never been seen before in unda. The midsole that supports the feet adopts a new "DUAL sole" structure that boldly extends from the conventional form. By expanding three-dimensionally, a visual sense of volume is added, and a presence like sneakers is added to the feet. Of course, goyemon's unique cushioning is still present, providing a comfortable fit that you can confidently choose for walking around town or long-distance travel. And another detail that symbolizes this model is the "overlapping piss name". The double piss names on the left and right heels are a design accent that embodies the name "DUAL". "unda DUAL" has been finished as a pair that fits modern life while inheriting the aesthetic sense behind tradition." M (25.5cm~27cm)
