The BIRKENSTOCK Boston Nova is a modern interpretation of the classic Boston model with a futuristic touch. The shoe can be made to fit perfectly thanks to the innovative G-hook buckle that offers optimum support. Thanks to its two components, the sole promotes stability and comfort. It comprises a cushioning midsole made from EVA and a slip-resistant outsole made from genuine rubber. The upper is made from winter-proof felt in combination with nubuck leather.
