When the light shines on the photocatalyst, the electrons in the material are rearranged and they become more reactive. These electrons are then able to react with the water in the air and break it apart into 2 radicals. A radical is an extremely reactive molecule. These radicals then react with the pollutants and cause them to break down into non-harmful chemicals.

The Catalytic Clothing technology is designed to breakdown the pollutants straight away. However, some pollutants may become attached without being broken down. In this case, the pollutants will be washed off during subsequent laundering. This actually already happens with normal clothing.

The photocatalyst is delivered to the surface of the clothing during the traditional laundry procedure as an additive within a standard product such as a fabric conditioner. The active agent is packaged within a shell that is attracted towards, and subsequently binds to, the surface of the clothing during the washing cycle.

With Nadi X, haptic vibrations are built into a full physical language, allowing the technology to communicate feedback to help correct your form and achieve your fitness goals. The frequency and intensity of each vibration changes based on the body position and angle. This real time body tactile technology will change the way we interact with ourselves.

The visual impact is not the only special feature of this jacket: the outer fabric is a monofilament of nylon and steel with a transparent polyurethane film that protects the optical fibers and lets the light pass through it, creating an effect of depth. The inner fabric provides maximum protection from the cold thanks to a special aluminium coating that reflects body heat.

By using subtle vibrations, we help the wearer navigate the city by indicating when to turn left or right. The frequency and intensity of each vibration changes based on the intended instruction: soft left, merge left and hard left each differ in body placement and intensity.

All Wah brings a new level of freedom to guitar playing, with the sole of the All Star transforming foot movement into Wah modulation, using cutting-edge micro-sensor technology.

Simply move your foot as you would using a traditional Wah pedal, and the sneaker does the rest, communicating wirelessly via Bluetooth to the Wah Box for the Wah effect. The All Wah can be used in a classic stage set-up with an Amp or connected to a MAC or iPhone.

Oh wait, there already are interactive sneakers with a display out there.
ShiftWear only have one disadvantage. It's kinda stillborn. They lack the element of magic and seem to be a bit dull. Let's take a look at how they're made.

As for April 2017, they are still in pre-order stage, and, as seen in Jan 2017 Youtube update, they're only starting to actually prototype the shoe for production. The display they are using is LED and not very flexible. It is also glossy and only covers a portion of the shoe on its side.

A pair of those will be $500. Although they initially had plans to go cheaper:

Also LED, but only one colour: white. Looks classy. Tremendous Indiegogo success.
MSRP (manufacturer's suggested retail price) is $325.
