This winter, Ccilu presents an award-winning
answer to the elements: Diffusion.

The typical winter boot is heavy and thick. That clunkiness makes it difficult to get around. Style is sacrificed for utility, while functionality is also lost in the mix. For these reasons, we were inspired to design winter boots that not only are lightweight, but also have a fun, forward-looking style. After all, Ccilu is known throughout the world for its lightweight shoes, sandals and sneakers that bridge technology and style. This year, especially for our first winter in the US, why not extend our philosophy to winter boots?

We could not be happier with the results! In 2017, Ccilu’s Diffusion winter boot collection won the Golden A’ Design Award in the the Footwear, Shoes and Boots Design Category. A'Design is the world’s largest international design competition, voted on by the International Design Academy, a grand jury panel consisting of influential press members, established designers, leading academics and prominent entrepreneurs worldwide.

Ccilu’s unique marriage of style and tech is part of our DNA. We made a name for ourselves with designs using our revolutionary SKIVE-ON and eco-friendly CCILUCELL technologies. Founded in Japan in 2011, Ccilu’s first product, “Amazon Summer,” won the Silver Award of the Best Designed Products in the 72nd Tokyo International Gift Show. By 2017, our brand was being sold in more than 60 countries. Now, Ccilu has arrived in the USA.

Liberate yourself from the elements...and your next step is clear.
