![]() The other new feature of the 4DFWD midsole is that its lattice comprises of bow-tie shapes. The 4DFWD lattice is made of 39% bio-based material and it also offers 23% more cushioning than the previous 4D midsole in the AlphaEDGE. The lattice is produced by using a chemical process using light and oxygen which transitions a liquid to a solid. Midsole The midsole of the 4DFWD consists of no foam but a full-length, 3D printed lattice. There is plenty of space in the midfoot and forefoot while the knit is also super stretchy so the 4DFWD is suitable for wide footed runners and runners with voluminous feet. The fit of the 4DFWD runs a half size large because of how stretchy the Primeknit is, so you need to get it a half size down from your normal Adidas size for the perfect fit. The 3 stripes on both the lateral and medial sides of the midfoot are reflective for low-light training. The heel tab is also made from a stretchy knit with a soft inner lining to not irritate the Achilles.īeing a full bootie construction, the lace loops are attached on the outside of the vamp so there are no double last row eyelets to do a runner's knot. The heel tab flares upwards to create a modern “elf heel” look. There are soft foam pods on the inside of the heel designed to grip onto your ankle and prevent heel slippage. The heel has an internal counter which locks your heel in place and provides support. It's soft to the touch and very stretchy with an extremely comfortable, slipper-like fit. The 4DFWD has a relaxed, sock-like knitted upper made from Primeknit. Drop: 11 mm (heel: 34 mm / forefoot: 23 mm).It also has a 10 mm higher heel stack height and a 9 mm higher forefoot stack. In other words, the midsole redirects vertical impact forces into horizontal forward motion.Ĭompared to the previous version, the AlphaEDGE 4D, the 4DFWD weighs 37 g more. The 4DFWD is different to its predecessors in that it uses a bowtie-shaped cell that compresses forward upon vertical impact. ![]() The 4DFWD is the third generation in the 4D product line. It had thicker struts directly under the strike of the runner's heel. In 2018, the AlphaEDGE was launched which was tuned for more versatile performance. Together, the two companies produced the first 3D printed shoe, the 4D Futurecraft in 2017. ![]() Carbon is a 3D printing technology company based in Redwood City, California. They clearly see 3D printing as the future of running shoes by the amount of money and effort they have invested in this technology.Īdidas partnered with Carbon back in 2016 to develop their 4D range of 3D printed midsoles. When it comes to 3D printed midsoles, Adidas is light-years ahead of any other brand.
