BIRKENSTOCK Birkenstock. Shipped after removing from the box and including the box. BLUE FOOTBED TRADITION Size: 25-25.5cm The Blue Footbed Tradition is an insole designed with a lower transverse arch and a higher longitudinal arch, so it can be used with heeled shoes such as leather shoes and pumps. The main body uses cork, and the elasticity and hardness unique to cork accurately support the three arches of the sole. It is a 3/4 size to accommodate the forefoot, which varies in length depending on the person, so you can experience the functionality of Birkenstock without changing the shoe size, even with thin or narrow shoes. * The three arches of the sole: The undulations called the inner longitudinal arch, the outer longitudinal arch, and the transverse arch have the function of supporting the body in a balanced way. ■ Features Recommended for heeled shoes, formal shoes, leather shoes, and shoes with unstable heels (shoes that are soft and roomy, or shoes with flat and thin soles can be said to be shoes with unstable heels). Easy to install, just put it in your shoes. No need to fix it with adhesive tape, so you can replace it with various shoes, making it a wallet-friendly insole ◎ * The insole may not fit depending on the height of the heel. In 1896, Konrad Birkenstock of Germany first developed a resilient footbed.
