The Think! sandal KOAK is made of particularly soft, chrome-free tanned smooth leather. The straps of colour-coordinated leathers give the deep footbed sandal the typical Think! look. The colourful outsole is a special highlight. All three straps are individually adjustable to the foot with a Velcro fastener. This ensures a firm hold in the shoe and the soft leather prevents pressure points. The leather lining and footbed as well as the cushioning sole ensure an incomparable wearing comfort.
