Nike and their Running Shoes Technology

Nike Technologies

Nike, Inc. has a history of developing innovative and new impact protection systems.
Starting with the Waffle Trainer to the Shox columns developed in 2001, certain technologies can only be found in genuine Nike shoes.
Since it early stages, Nike research facilities had evolved to the present 13,000 square feet building designated to the constant improvements of technologies, where research is divided into three parts:

*Biomechanics: how the body moves
*Physiology: how the body works specially under stress.
*Sensory/Perception: the evaluation of how a product works, feels and wears.

Nike products undergo a rigorous testing process that covers a wide variety of testing surfaces (regular basketball hardwood, soccer turf, running tracks and endless outdoor testing on various terrains), and four important factors are taking into account, geography, gender, age and skill level.
All of this combined with the results of about a dozen other tests are used to develop new, user-friendly products.

Impact Protection:

Nike employs a variety of cushioning systems in their products. Cushioning systems need to reduce shock, distribute pressure, protect from impact and offer comfort.
The four cushioning systems pioneered and sold by Nike are Nike Air, Nike Air Max, Nike Air Zoom, and Nike Shox.

Nike Air

Nike Air was the first air technology developed at Nike, and it changed the way people thought about cushioning. It remains a standard for impact protection more than 20 years after its creation. The Nike Air made from pressurized gas inside a tough yet flexible urethane plastic capsule. The large molecules of gas prevent it from escaping the bag. The Air-Sole units are encapsulated in the midsole beneath the heel, forefoot, or in both locations depending on the shoe and the needs of the athlete for whom the shoe was designed. The Air-Sole works to cushion the foot by compressing and reduces the force of the impact and then immediately recovers its original shape, ready for the next impact.

Nike Max Air / Air Max

Nike Max Air, the maximum in impact cushioning, is designed to take brutal, repetitive impacts and minimize their effects on the body and your performance. Air Max units are made through a technique called “blow-molding”, allowing for the greatest volume of Nike Air without weakening the Air-Sole unit. Duel-pressure cushioning addresses the need for protection and rear foot stability. The hallmark of the Air Max technology is a visible air unit in the heel. The Air Max provides athletes with full-length impact protection.

Nike Zoom Air/Air Zoom

This lightweight, super-responsive, and ultra thin Air unit brings the foot closer to the ground for the ultimate feel and great maneuverability. Used primarily for basketball shoes, shoes built with the Air Zoom tend to be light and responsive with excellent “ground-feel”.

The Air Zoom unit starts with two fabric layers connected by thousands of vertical fibers, each attached at both ends to a fabric layer. These fibers are then surrounded with pressurized gas inside a Nike Air unit. While the pressurized air exerts and outward force, like a full balloon, the fibers are placed in tension and exert an opposing inward force to keep the air bag from popping or bulging. On impact, the air bag compresses to relieve the tension on the fibers. After impact, the pressurize gas expands the air bag and places tension on those fibers. The fibers compress on impact and then spring back immediately. The advantage to the Air Zoom is that it is incredibly thin and light, but it provides excellent impact cushioning while allowing the wearer to feel the surface he or she is in.

Nike Shox

Nike Free technology is a combination of impact protection and outsole technology. This light-weight, highly flexible shoe simulates the effects of barefoot running and distributes the landing pressure over a larger area to reduce stress on the legs, knees, and back.

Biomechanical studies show that allowing your feet the full range of its natural movement builds strength and reduces injury. In answer to the demand of would-be barefoot runners worried about protecting their feet from the elements, Nike created an outsole with deeply segmented grooves that mimic the natural pressure patterns of a barefoot landing. The forefoot area allows a greater flex of the toes for a natural grip that creates stability and pinpoint turns.

Nike Sphere React:

Nike Sphere React fabric is built to breathe. When an athlete sweats, this highly breathable fabric opens up, increasing airflow across the skin and reducing cling. The result is a cooling effect on the skin that allows athletes to perform in greater comfort. With three different Sphere React fabrics to suit your workout style, you’ll stay cool, dry and protected from the elements.

Nike Sphere Dry:

This double-brushed microfiber fleece retains energy and resists heat loss. It provides maximum insulation from cold and wind with minimal weight and bulk, and is ideal for any cold weather activities that require insulation. Can be worn alone or as part of a multi-layering system.

Nike Dri-FIT:

This high-performance microfiber polyester fabric actually pulls sweat away from the body and transports it to the fabric surface – where it evaporates and leaves the skin cool and dry. It’s all you need for hot days, and a critical base layer for cold days.

Nike Therma-FIT:

This double-brushed microfiber fleece retains energy and resists heat loss. It provides maximum insulation from cold and wind with minimal weight and bulk, and is ideal for any cold weather activities that require insulation. Can be worn alone or as part of a multi-layering system.

FlyWire

Nike used suspension bridge design as inspiration to create
FlyWire, a system that uses powerful Vectran ™ fibre cables to support the foot.

Unlike typical shoes that allow the foot to slide inside the
shoe, FlyWire keeps the foot locked down tight, eliminating
millimeters of movement with each stride.
FlyWire cables wrap around your foot much like tendons.
Any extra material is only there to keep out rocks and dirt. It’s an innovation that allows Nike designers to cut shoe weight by up to 50%.

“Vectran” is used to make FlyWire cables, it’s a high
performance multifilament yarn spun from liquid crystal polymer.
Pound for pound, it’s five times stronger than steel yet is extremely flexible.

LunarLite

Designer Kevin Hoffer found himself looking at images of astronauts bouncing around in space and wanted to recreate this feeling in a shoe.
So he turned to the aerospace industry to help develop Nike’s lightest, most responsive cushioning material ever.

Nike Sports Research Lab studies show that LunarLite Foam spread pressure across the whole foot, thus
reducing impact on fragile bones.
LunarLite Foam cushioning is compared to Phylon, Nike’s next lightest performance foam.

SHOES TECHNOLOGIES

I would like to thanks my dear friend Lucy for all the time that she spent writing this wonderful post for all of us enthusiastic of athletic shoes . . .

The inspiration for this post came to me on Monday, as I was looking for some Adidas shoes.
After 6 minutes of just watching soccer shoes for my brother, I finally choose the one I wanted, a Predator PowerSwerve in Green, which I liked because of its design…
While I searched inside my tote for my wallet, I spotted a pair of metallic blue ones an F50.8 Tunit; I got to them as quickly as I could since a tall and creepy looking guy was looking at them from a distance with the intention of buying them.
Once I got them I couldn’t help to turn around and look at the tall man with my victory smile of “I got to them first”. (Obviously there were more at the store but it was fun anyway!)

With both pairs of shoes in front of me, I was in a dilemma, which one should I pick?
To me the only difference was the color, so I look for some male advice and asked one of the salesclerk at the shoes store, he told me that the green ones were better and I obviously asked why, he responded saying
Cause they have PowerPulse technology ” I asked him what was that and he just told me “It’s a technology” ….?#@_? ¿

With that answer I wasn’t convinced at all of taking the green ones, so I bought the F.50 Tunit in metallic blue.

I would like to dedicate this post to my favorite salesclerk!!, and of course to all of those who just want to know what a3,EVA,Clima Cool means in Adidas shoes…
Enjoy! 🙂

*Since Adidas technologies are quite a lot, I’ll have to leave Nike and other brands for another post…otherwise I would be typing forever”

Shoe Parts and technologies

When it comes to sneaker technology, shoes are divided into three major areas: the upper, the midsole, and the outsole (for further information check our shoe parts post). Depending on the materials and combinations used, one model of sneaker can vary greatly from another.

The Upper

Uppers, the top part of the shoe with the laces, fancy designs and bright colors that holds the shoe together, usually come in one of three materials, leather, synthetic leather, and mesh.
Special editions, retro and vintage models, Converse and casual shoes like the Nike Vandal, the Air Force 1, and the Nike After Party for women may have a canvas upper. The most famous shoes to have an all canvas upper are the Converse All Stars.

The Midsole

Midsoles are used to cushion and provide support and protection for the foot. There are four types of materials used in commercially produced sneakers. Midsoles are often constructed of a combination of materials. Midsole materials are Phylon, polyurethane, Phylite, and EVA.

Phylon

Phylon is very lightweight, low-profile and responsive. Phylon is made of EVA foam pellets that are compressed, heat expanded and then cooled in a mold. Compression-molded Phylon Midsoles can be sculpted into a variety of designs that are identified by their fine wrinkles.

PU or Polyurethane

PU is the most dense, durable and stable midsole material. PU is poured into a mold to create a firm midsole that provides maximum protection from impact. PU is identified by its smooth rubbery feel and tendency to turn yellow with age. PU is the heaviest midsole material, but it is also the most durable

Phylite

Phylite is an injection-molded unit made of a combination of 60% Phylon and 40% rubber. Phylite is lighter than rubber, but heavier than Phylon and functions as both midsole and outsole. By eliminating a separate midsole and outsole the weight of the shoe is greatly reduced and flexibility is increased.

EVA

EVA is soft, light and flexible. It is the least expensive midsole material and is often used in entry-level shoes. Midsoles are cut and shaped from flat sheets of EVA foam. EVA will compress and become flat over time as the air trapped within the foam is squeezed out. Once EVA is compacted, it does not return to its original shape and no longer provides cushioning. EVA compresses faster than other midsole materials.
