In June 2021, sales started for sneakers that use cellulose nanofiber ^(*1) "nanoforest®". This product is jointly developed and marketed by Marubeni and Chuetsu Pulp Co., Ltd. (hereinafter, “Chuetsu”).

The cellulose nanofiber “nanoforest®” is incorporated as an additive in the rubber sole of the sneaker. The models that have the “nanoforest®” sole are the “SPINGLE MOVE” SPM-172 and SPM-295, a shoe brand by Spingle Company Co.,Ltd. ^(*2) which is a handmade shoes manufacturer located in Fuchu City, Hiroshima Prefecture.

The use of “Rubear cellulose nanofiber soles”, in which bio-material is compounded into the rubber, improves wear resistance by 40% as compared with conventional rubber soles, making the soles in these shoes both earth-friendly and durable.

Marubeni will continue to develop further practical applications in the cellulose nanofiber business field with Chuetsu.
