The shape of the Ultra Boost 4D Uncages is reminiscent of Adidas Consortium’s Futurecraft 4D which was released in 2019. The shoe comes in a Core Black/Blue Spirit colourway, perhaps to mimic the colours of the deep ocean. The design incorporates 4D printing for the midsole whilst using recycled ocean waste in the uppers to create a shoe that is both sleek and sustainable.
The trainers feature all black uppers, with wavy blue spirit stitching running from heel to forefoot. The blue stitching adds an ocean like texture mirroring waves in the sea. The branding is very subtle, if you look closely you will find the 3 stripe Adidas branding on the midfoot, as well as Adidas tongue branding where the logo is embroidered on in black. The Parley branding can be found on the insole of the shoe. The midsole has been 4D printed and the outsole is made from a black rubber. The shoe has been crafted with recycled ocean plastic that has been taken from the worst affected beaches and oceans, by purchasing a pair you know that you are doing your bit to clear up the oceans. Sustainable footwear is definitely the way forwards.
