Gruppo Manifatture Italiane, composed of River Group, Calzaturificio Energy and Calzaturificio Claudia, is a hub of excellence in the Made in Italy production of sneakers and formal shoes of the highest quality for prestigious luxury brands.
The group has three production sites in Tuscany and three tomaifices abroad, including one located in Albania (Alba Group) and two in Tunisia (MCT and Dana), which operate exclusively for the group.

In January 2018, CPEF III acquired a majority stake in the River Group – composed of River Group and Calzaturificio Energy, based in Fucecchio (FI) – through a leveraged buy-out operation.

In October 2019, CPEF III joined River with another Italian shoe excellence, Calzaturificio Claudia, based in Capannori (LU), creating the Gruppo Manifatture Italiane, the first aggregation in the sector.

In December 2025, the company was the subject of a GP-led transaction, moving from the CPEF III fund to the CAPEF continuation fund
