The first thing to consider with any footwear, including athletic shoes, is comfort. If a shoe isn’t comfortable, there is no use in wearing it. The poorly fitting shoes could cause blisters, overall discomfort, balance problems and even sport injuries.
The emergence of ever popular Nike Air Force Ones played a major role in this transition both due to their look and their effectiveness when it comes to sporting activities. Court shoes and cross trainers have their tread optimized for lateral or side-to-side stability. Court shoes include shoes for tennis, basketball, and volleyball. Most court sports require the body to move forward, backward, and side-to-side.
Nike processes and recycles the footwear to make sports surfaces for basketball courts, tennis courts, running tracks, and playgrounds. Runners can jog up and down aisles. Running shoes are primarily made to absorb shock as the heel strikes the ground. In contrast, tennis shoes provide more side-to-side stability.
Running shoes are built for straight forward impact, not the sharp sideways movements of tennis. Tennis shoes are not good for running since they have a completely different cushion pattern. Running shoes usually have a slight heel elevation to help decrease the stress to the Achilles tendon. Running shoes also have a larger toe box, more shock absorption and improved foot control than a tennis shoe.
Runners do the same thing. When you run in cushioned shoes, your feet are pushing through the soles in search of a hard, stable platform. Running shoes have no heel and this provides the necessary leverage for toe spring, which propels the runners legs forward. Competition betwen shoe companies was fierce and many athletes were unofficially approached to wear brand names.
Footwear manufacturers, including many athletic shoe companies themselves, jumped into this niche in the early 1990s and began offering comfortable quasi-athletic shoes made with leather uppers and an emphasis on unique styling. This trend coincided with a general relaxation of office dress codes and created a new half-casual, half-workplace type of shoe.
