The 4D sole from Adidas is been around for quite some time and it’s never dropping to lower segments for good reason. The 4D technology that Adidas uses to conjure the Adidas 4DFWD from the depths of science-y dungeons is quite fascinating. It uses Carbon’s Digital Light Synthesis to 3D print the midsole for these kicks and many other like these that came before it. As time progresses, tech innovations also run to catch up and this time the 3D printed midsole has been tailored for running enthusiasts.
Unlike the Boost midsole which is designed to be comfortable for long runs and also help cushion your strides, the 3D printed midsole on 4DFWD is specifically designed to reduce braking force. What that means is that if the Adidas UltraBoost 21 offer comfort for marathon runners, the Adidas 4DFWD offer the push to go even longer distances. The lattice midsole structure is made from bow-tie shaped FWD cells that are engineered to compress forward upon vertical impact. Imagine throwing a ball vertically down and instead of bouncing right back up, it moves horizontally forward. That’s pretty much what the bow-tie shaped cells in the mesh midsole do. So when you run, they return energy to move you forward. It’s incredible how much can be achieved with such adjusting a few nobs, pushing a few buttons and cheering on the helpful crowd at Carbon, Inc. But let’s face it, it wasn’t that simple. Adidas says that the bow-tie shape is the one they selected after scanning through five million possible lattice structure options and it’s even made of 39% bio-based material.
Nerdy stuff aside, how do they perform? Well, as you’d expect! The bow-tie structure is no joke. You can feel the energy return when running long distances. Albeit, these are not meant to be used as lifestyle kicks. As much as we’d like to wear them to Ikea (which we did), Adidas’ own Boost midsole proved to be a more comfortable wear for everyday use. If you want the best for running, these are up there with the best!
The upper is made from 50% recycled material as well and is as breathable as the Primeknit+ upper that’s on the Adidas UB21. The sock-like fit is also quite similar to the UB21 but it’s still not as snug. That’s to say the upper doesn’t completely hug your feet but it’s enough for a secure fit. If you have wide feet, they might fit like a glove. The iridescent finish on the three stripes is decreet yet classy. The three stripes are glued to the upper here unlike the UB21 which has a separate mid-cage that is stitched to the upper. It’s also the reason why the UB21 feel more tightly compressed to your feet than these.
It’s clear that at this point that the 4DFWD are for the people who want the best that has come from Adidas’ R&D spendings. The UltraBoost series still remains a fan favourite when it comes to everyday running. While the 4DFWD are equal with the UB21 in all seriousness, they can sometimes feel like an indulgence. But an indulgence well spent on running. If you have the bank for 4DFWD, it’ll make a great statement to your wardrobe and if you’re serious about running, these will prove their worth on track as well!
