Adidas has released a new variant of its 3D-printed Climacool shoes with laces so you can adjust their fit and potentially tone down how tightly they hug your feet. Featuring a breathable lattice structure created through an additive printing process, the shoes have previously only been available as slip-ons in a single off-white colorway, but now feature a black tongue and laces potentially making them look less like an experiment in shoe design and more like a regular sneaker.

The shoe’s main structure is still 3D-printed as a single piece in a process that Adidas says “takes approximately 24 hours and includes spinning, baking, and compression using high-tech polymers.” The upper portion of the Climacool Laced features a slightly different design than the slip-ons that now incorporates printed eyelets, but the tongue and laces are made from different materials added afterwards that aren’t 3D-printed.

The new version will potentially make the Climacool more comfortable and compatible with a wider variety of foot sizes while retaining the unique features of their 3D-printed lattice structure that was breathable and fast-drying.
