The brand, founded in 1774 in Germany, is known for its quality, comfortable and eco-friendly designs. Birkenstock is now available in 90 countries worldwide.

The brand has 2 main product lines:

• Leather products, oak soles – also known as CLASSIC (traditional) series, is a traditional product line that has been researched and gradually perfected from 1774 to the present. The product line is known for its very special soles. Constructed according to a standard foot structure, manufactured using oak wood and natural rubber, it will slowly adjust and transform into the shape of the user's foot after about 2 weeks. From there, the user will feel the sole holding the foot extremely comfortable. Each pair of Birkenstock, will only have 1 owner.

The disadvantage of the Classic line is that it has poor water resistance because all sandal straps use leather. Requires careful use. However, when used and preserved well, the product's shelf life can be up to 8, 10 years. There have been many customers around the world sharing their sandals with their record time on popular social networking sites.

• EVA plastic products – also known as EVA series, is a product line designed based on traditional oak soles, still ensuring comfort for the soles when used but 100% water resistant. Suitable for use when going to the beach, swimming, walking in the garden, and using it when it rains.

High-quality EVA plastic features ultralight (completely floating on water), skin-friendly and completely non-irritating, colorful, water-resistant and easy to clean.
