A limited collection that combines TRETORN’s tradition of rubber boots with Dutch KASSL’s modern design, this unique combination takes classic models and gives them a new, updated look where both function and comfort are prioritised. The Eefje Mules are a rubber modern interpretation of the classic clog. The silhouette features a minimalist design with clean lines and a chunky sole, making it a key piece in the urban wardrobe. The shoe is handcrafted from FSC-certified natural rubber, designed for better grip. The shoe’s simplicity works equally well for casual and more dressed-up occasions.
