Adidas ultra 4d 512/19/2023 ![]() ![]() 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. Because there is no structure to it, your heel might end up floating around if the size is too big.Adidas has been working away on 3D printed midsoles for several years now. We rated it 1 out of 5, where 1 is the most flexible. One more point in favor of sizing down is the shoe's highly flexible heel. On its official product page, Adidas actually recommends that you grab a half-size down for a snugger fit. It means that the Adidas 4DFWD has promising durability.īecause of its stretchy knit upper, this kick can become too loose over time. In our experience, the outsole's firmness is proportional to its durability. ![]() Based on our durometer measurement, it is 9% harder than average. The rubber compound also turned out to be impressively firm. Indeed, we measured the rubber layer at 4 mm while the average for road shoes is 3.4 mm. Even though it is not the famous Continental rubber that is often used by the brand, the outsole still delivered. The shoe is lined with a generous layer of rubber that instills confidence. An MSRP of $200 is significantly more expensive than the average $130 for Adidas running shoes.Įxpect well over 500 miles from the Adidas 4DFWD Its weightiness in the area of pricing is a valid cause for concern too. We found that the outriggers on the sole really help in making the shoe feel more stable. Given the shoe's tricky midsole design, having a wide and stable base is essential to prevent the runner from wobbling. Stability is not compromised in the 4DFWD The average among running shoes is 4.5 mm. This is right at the average of daily running shoes.Īs for the heel-to-toe drop, we measured it at 8.9 mm, which is also typical for this category.ĭisclaimer: All of our stack measurements are taken with the insole included.Ĭhecking the insole thickness in the heel area, we found that it is well-cushioned at 4.7 mm. But based on our caliper measurements, the midsole is 33.3 mm thick in the heel. Measuring stack height is also tricky with the 4DFWD. After 20 minutes in the freezer, we found that this Adidas shoe firmed up by 21%. However, when the lattice construction comes to life on the run, it creates a very plush underfoot sensation.īut keep in mind that in cold weather, the midsole will get firmer. Our measurement shows that the 4DFWD is 33% firmer than average. Please take our durometer measurement with a grain of salt given that this is not a foam. Measuring the shoe's cushioning softness was quite a challenge. Your browser does not support the video tag. ![]()
