Tretorn X Kassl Editions Gus Gummistövel
— Rubber Boot Men

The collaboration between TRETORN and KASSL Editions. A limited collection that combines TRETORN’s tradition of rubber boots with Dutch KASSL’s modern design. This unique shoe collection takes classic models and gives them a new, updated look where both function and comfort are central.






Gus is a men’s shoe with a modern silhouette, combining Tretorn’s hybrid shoe with the classic loafer. The rubber boot features a smooth natural rubber surface at the front and a subtle tongue on the instep, referencing the classic loafer design. The shoe is waterproof, and the outsole is handcrafted from FSC-certified natural rubber, offering optimal grip on all surfaces. Its sturdy construction is complemented by a metal shank in the sole for extra stability. The removable BLOOM insole makes it easy to air the shoe when needed, and the insole, made from algae, makes the shoe more environmentally friendly. The soft neoprene lining provides a comfortable fit and is both warm and quick-drying.

Gus is designed for a wide range of uses. With its combination of function and fashion, it is ideal for an urban lifestyle. Whether facing rain or cold, Gus offers both style and protection for the challenges of everyday life.
