24 Kilates from Barcelona, Spain collaborated with the Italian sneaker brand Diadora to create the 24 Kilates x Diadora N9000 "Sombra" in December 2014. This sneaker is part of a two-part collaboration collection, with the Sombra being the second release following the lighter "Sol" version. Featuring rich, deep colors, the Diadora Sombra embodies the concept of transitioning from day to night, with soft grey suede adorning the toe box and mudguard, complemented by light-tan suede overlays at the mid-foot and heel. The design seamlessly illustrates the shift from day to night, as the grey tones fade into deep black detailing on the eye stays, tongue, and inner sock liner. The iconic Diadora logo is represented in soft grey leather with a grey nylon underlay on the mid-foot. The dark 3M tongue showcases the 24K branding, and the phrase "Sol y Sombra" is found on the heel. Originally priced at $212 and made available at select Diadora retailers worldwide, the sneaker gained massive popularity especially due to the success of its pack-partner. The 24 Kilates x Diadora N9000 "Sombra" remains a significant piece in the legacy of the Diadora N9000 line.
