Moritz Engel – CALYX
by Moritz Engel
CALYX is a minimalist climbing sandal. Designed for optimal hygiene and maintenance, it reduces the conventional mixed-material, climbing shoe to a textile-free exoskeleton. It is built around a durable rubber core with replaceable, wear-indicating Vibram soles and features "Debond-on-Demand" adhesive, which allows for resoling during use and separation for downcycling at the end of its life. While the sticky climbing shoe rubber soles provide the usual performance, a secure and adjustable fit is made possible by easily interchangeable laces. Thanks to its foldable and packable design, CALYX is ideal for the purist climber who strives for maximum feel and feedback with minimum weight.
