Adidas Climacool Grey Four Core Black — The 3D-printed sneaker you can buy

On May 2, 2025, adidas launched the Climacool globally, its first fully 3D-printed sneaker intended for the general public. It was developed with Carbon, the Silicon Valley company specializing in digital light synthesis, and is manufactured as a single lattice-structure piece: there is no separate upper, midsole, or outsole. The Grey Four Core Black is its most understated version.

The Climacool — one piece, 360-degree ventilation

With no laces or seams, you slip it on like a clog, while the lattice itself provides support, cushioning, and ventilation all at once. Air channels run through the sneaker across 360 degrees and, according to adidas laboratory tests, keep the surface of the foot around 3 ºC cooler. Each pair takes around 24 hours to print. Here, Grey Four covers the structure and Core Black finishes the base.

Materials and technology

  • Upper: 3D-printed lattice structure in Grey Four made using digital light synthesis, with no seams or bonded pieces
  • Interior: The same lattice, with variable density depending on the area to support the foot without an additional lining
  • Outsole: Integrated Core Black base, with cushioning defined by the geometry of the print itself

How to style the Adidas Climacool Grey Four Core Black

  • Mainland Spain and Portugal: 24–48 business hours
  • Rest of the European Union: 2–4 business days
  • Balearic Islands, Canary Islands, Madeira, Cyprus and Malta: 5–6 business days

Do you need it by a specific date? Ask us on WhatsApp before buying, and we’ll confirm whether it will arrive on time.

How much does shipping cost? Is there free shipping?

We ship across the European Union (not to Switzerland, the United Kingdom, Norway or Iceland). You’ll see the exact amount at checkout after entering your address, before paying. Free shipping doesn’t apply to large Pop Mart figures.

Are your products 100% authentic?

Yes. All our products are new and 100% authentic. Every item is inspected by our team before shipping and gets the Next Step Verified tag, confirming it has been verified and shipped directly by us.

Plus, manufacturing defects are covered for 14 calendar days after delivery, and Swatch watches come with the official manufacturer’s warranty.

What if it doesn’t fit? Exchanges and returns

You have 14 calendar days from receiving your order to request an exchange or return.

Changing sizes is easy: request the return from your account under My orders, indicate the size you want in the comments, and as soon as we receive the item, we’ll send you the new size at no shipping cost. There’s no need to place a new order.

We’ll provide the return label via WhatsApp (SEUR or UPS in mainland Spain; UPS for all other destinations). Its cost is the standard rate for your area, for example €6.95 in mainland Spain. The item must be unused and have the Next Step Verified tag intact.

What size should I choose?

For each product, you’ll find the model’s size guide. Always use the European size (EU) as your reference: it’s the most consistent across brands.

Not sure between two sizes? Message us on WhatsApp with your height, weight, and usual size: our assistant will recommend the right size in seconds, at any time.

My size isn’t listed or is on pre-order—what should I do?

If a product is marked as Pre-order, it isn’t in our warehouse right now, but we source it specifically for you through our supplier network within 1–10 business days and keep you updated by email every step of the way.

If your size isn’t listed on the product page, message us: we’ll check whether we can get it and let you know.
