    I wasn't comfortable, I wasn't happy it wasn't the best fit also I kind of felt that I should have gotten half a size or at least a full size up on this one but that best that doesn't change the fact that they felt that the 4d technology of the midsole here wasn't really up to par when compared to the other technologies that you see - cushioning technologies of Adidas and the different brands that are offering the same kind of thing.

    Printed via a revolutionary 4D Digital Light Synthesis process, adidas Futurecraft is unlike anything else in the world of sneakers. Boasting a signature mint green colorway, it’s both lightweight and durable

  • 93 / 100 | The Sole Line | Level 2 expert

    One of the most outstanding features of this shoe is the 4D printed midsole——a signature ash green printed one which is designed using a process called Digital Light Synthesis, a proprietary technology pioneered by California-based company Carbon. Hard as it might look to be, it is in fact very soft and springy if you put pressure on it with your hands. And this is how it functions——it is designed to provide multi-directional support and stability to an athlete’s feet.

    These shoes employ the 3D printed midsole deemed as 4D. It's a lot firmer and offers more support than Boost. I like this shoe a lot. What I don't like is the price point.

    The AlphaEdge4D sneaker is like nothing I have ever owned before; from the sleek design to the colours and comfort, this is something very unique. The first observation when unboxing is that they are much heavier than the boost technology, which makes sense as there more plastic material than previously. To wear they are very comfortable and feature a double tongue which make them easy to put on and feel very supported. The styling is futuristic, featuring a blend of grey shades, sharp patterns and the signature 4D green sole.

- The Adidas Alphaedge 4D is a futuristic running shoe that has been designed guided by years of athlete data. It is an innovative running shoe that delivers a unique and very interesting running experience. The Alphaedge 4D propels the runner into a realm of more future-forward technology. Adidas uses the Aramis 3D motion capture system which maps the runner’s movements to create a fit without pressure points of irritation.

- The most significant feature to the Alphaedge 4D is its Futurecraft found in the shoe’s midsole. It is a shoe technology which is unlike any other technology out in the market. It is a revolutionary 4D Digital Light Synthesis process that was developed by Adidas to ensure high-performance comfort. 

- This Adidas running shoe was made for cross-training, and it uses the Primeknit upper with strategically placed stitching to provide support where it is needed the most. It wraps the foot with an engineered fit for more targeted support that enhances the runner’s movement. The stitched in support zones are heat-pressed, TPU coated fibers that are stitched in the shoe to provided the targeted support and lightweight durability.

The Adidas Alphaedge 4D comes in standard medium D for men and medium B for women. This running shoe from Adidas was said to fit true to size, although the majority of users recommend to go half a size up than one's usual shoe size to guarantee a perfect fit.

One reviewer also stated that for those with narrow feet, it is best to stay with the usual size you would usually go for in an Adidas Ultra Boost, as the Alphaedge 4D will fit nicely with the roomy toe-box. But if you are someone that prefers a more snug fit, it is suggested to go half a size down. And if you have wider feet, then it is advised to also go with your Ultra Boost size because the shoe tends to be a little tight around the midfoot area.

The Adidas Alphaedge 4D incorporates the Continental Rubber into its outsole. It offers excellent traction and resilient grip. The continental rubber is inspired by tire technology which has unparalleled traction on wet and dry surfaces, making the runner secure with his or her footing during the ride. It also protects the feet during the impact, minimizing the risk of injuries while also improving performance at the same time. 

The Alphaedge 4D was designed to create and control energy that is why the shoe’s midsole was developed to provide high performance and comfort. Seventeen years of athlete data were studied in programming the Alphaedge 4D. The shoe’s midsole guarantees stability, support, comfort, and cushioning as the runner powers through their ride or training. 

The shoe’s midsole is powered by Futurecraft midsole. It is a unique shoe technology designed by Adidas in partnership with a Silicon Valley-based technology company called Carbon. The Futurecraft 4D was designed using Digital Light Synthesis in which light and oxygen turn liquid resins into a rugged, flexible base. They have engineered the physical midsole of the Alphaedge 4D to provide the ultimate personalized experience for all types of users. 

This neutral running shoe also has a heel zone that offers optimum cushioning. It absorbs and disperses shocks, which help reduces the impact on the foot, preventing any injury.

The Alphaedge 4D’s forefoot zone has also been structured to enhance forward motion, propelling the runner forward while increasing energy.

Lastly, the shoe’s transition zone makes sure that there is a smoother heel to toe transition for a more energized and dynamic ride.

The Adidas Alphaedge 4D's upper sports a futuristic design thanks to the use of Primeknit material. This material encases each foot in breathable comfort, and with its seamless construction, the Primeknit provides an irritation-free fit avoiding unwanted blisters while wearing the shoes. It is also lightweight and designed with motion in mind that is why this upper material adapts to the changing shape of the runner's foot throughout the gait cycle. 

The Primeknit upper also features stitched-in support zones which offer targeted support in areas where it is needed most. The Alphaedge 4D's Primeknit is constructed using a forged mesh which helps the upper of the shoe provide an abundance of flexibility, breathability, and support.

The perforations in the Primeknit upper do not only determine levels of support, but it also increases ventilation so that the feet remain cool, dry, and comfortable at all times. The mesh allows fresh air to circulate inside the shoe while, at the same time pushing hot, muggy air out to escape; creating a perfect microclimate for the runner's feet to thrive in.

The shoe's upper also guarantees lightweight durability and a secure, locked-in fit which is achieved with the lace closure system, avoiding shoe slippage. 

Lastly, it has a heel tab that helps with the easy on and off of the shoe.
