The one and only Tradi Zori. Inspired by the traditional Japanese thong sandals, this collab between Havaianas and the LA brand, Market, features thermochromic technology on the black soles. This means that once you put them on, your body heat turns the soles red! Is that hot or what?!

The effects and durability of thermochromic technology may vary depending on climatic conditions, temperature and frequency of use to which it is exposed, and it may even lose its original characteristics.The thermal effect starts to appear around 31 degrees celsius. After a long time of use or exposure to high temperatures, the effect decreases, making the marking on the sole permanent.
