The sign-up for a chance to buy one of the limited shoes is from May 5 th to May 16 th. Stack Height: 21.2mm / 32.5mm, 10 mm dropĪvailable May-August. Loud squishy noise with every landing is distracting JeffĮstimated Weight: men's 11.55 oz / 327g (US9).Laces are way too long, had to quintuple knot to make them appropriate sized Jeff.Less than ideal fit, especially at the rear on my narrower right foot. For actual running upper doesn’t keep up with the platform as well as it could with a non knit Sam.Weight at 11.55 oz / 327g US 9 is up there for a modern run trainer as is pricing at $200 Sam.Toe box has decent width and stretch making it effectively bigger Sam.Sharp (and positive) contrast with UB 21 and its highly directed rigid approach, more lumbering ride and additional almost 1 oz additional weight Sam.Relatively secure stretch knit upper with decent toe box hold, a change for such uppers Sam.

4D now today a new and compelling midsole technology for actual running or are we still at the concept car technology platform demo stage? For sure 2020 and now 2021 have ushered in an era of run shoe midsole innovation with primarily super light energetic foams and here we have a completely different approach. Jeff and I received samples prior to receiving any of the information above so we were able to test without any of the tech data and marketing and then continued testing after receiving it. PRIMEKNIT+ UPPER: Using historical mapping data, the PRIMEKNIT+ upper has been tailored to work perfectly in tune with the adidas 4DFWD midsole, supporting the runner every move forward with a sock-like fit, while letting the foot breathe freely MIDSOLE INNOVATION: A unique bowtie-shaped FWD CELL redirects energy from each step's impact to create horizontal forward motion LATTICE CONSTRUCT: Made of 39% bio-based 3D material, offering 23% more cushioning and generating over three times as much forward motion when compared to previous generations of 4D midsole under vertical loading in mechanical testing conditions The key features called out by adidas are: To create this midsole, adidas and partner Carbon combine athlete data and Carbon’s Digital Light Synthesis TM technology to produce the precision tuned 3D printed midsoles with the ability to fine tune midsoles to specific patterns of movement. Selected from one of five million possible lattice structures and made of 39% bio-based material, the bowtie-shaped FWD CELL according to adidas has been specifically coded to compress forward upon vertical impact to redirect vertical load energy to horizontal energy in the stride while reducing peak breaking force by an average of 15% to deliver running economy comparable to Ultraboost. In the 4DFWD the FWD CELL lattice is said to be designed to deliver up to 3 times more forward motion in mechanical lab testing compared to previous generations of the technology.

The outsole is made of full length, single density Continental rubber for good durability and traction both inside and outdoors.Adidas has been working away on 3D printed midsoles for several years now. It doesn't contain Adidas' Ultraboost material, but gives the same level of comfort. The soft and squishy 3D printed midsole remains the same shade in all colorways and looks like something from the future. The internal 3D moulded heel counter, and Primeknit textile upper give a snug and secure fit to hold the foot in place. This running shoe is not for someone who wants to blend in and go unnoticed! This is balanced out with a thin, breathable lightweight upper in a range of eye catching and style conscious patterns. This technology sacrifices the weight of the shoe, coming in on the heavier side at 12.9oz. This results in a smooth and stable ride, with the right balance of support under the arch of the foot. What this delivers underfoot is a softer heel landing, and a firmer midsole as you move to the front of the foot. Insights from this data have been used to 3D print the midsole lattice structure to cushion and support your feet in the areas they most need it. This data looked at pressure maps from each time the runners landed. The 4D Run 1.0 features a digitally printed midsole, based on 17 years of analysed athlete data from 4,000 runners. The Adidas 4D Run 1.0 is a stand-out-from-the-crowd, technology packed, neutral running and training shoe.
