One of the best pairs of shoes that I have -- and wear regularly -- is my pair of cross trainers. I do not run much, nor do I play organized sports. But, I do like to shoot around a little or play baseball or soccer with my son and husband. And I enjoy tennis. But I really can't justify spending the money for a particular pair of shoes for each sport. So instead, I wear cross trainers.
A pair of cross trainers can serve as a sort of all purpose athletic shoe. They are reasonably comfortable, and they are capable of providing support for the amount of activity that I do in them. Here are the parts of cross trainers, and what makes them ideal for all different sports.
Cross Trainer Outsoles
The key to the versatility of cross trainers is the part of the shoe known as the outsoles. (the bottom of the shoes) On most shoes, the outsoles are very wide, as to offer good stability, and is ideal for side to side movement. Most outsoles are made from some sort of carbon rubber (which is quite durable) for the sturdier varieties. These will hold up longer, and will work well for outdoor sports activities.
If you are looking for flexibility, however, look for cross trainers that have a mixture of carbon rubber and blown rubber. Blown rubber is lighter and softer. These shoes are ideal for frequent use and offer a higher level of comfort while playing sports. It is important to check to make sure that your outsoles are approved for indoor activities, since many gyms restrict the types of shoes you wear; they do not want your shoes marking up the gym's floor.
Midsoles
The midsole is that area between where your foot rests and the bottom of the shoe. One of the things that contributes to the comfort of cross trainers is the fact that there is cushioning at the heel and at the front of the shoe. You want midsoles that are fairly durable, yet somewhat flexible. Look for polyurethane, since it is more dense and will add stability to your shoe. EVA may provide for a lighter shoe, but it is less durable. In many cases, cross trainers will combine EA and polyurethane to produce a shoe that is lighter, but still durable and stable.
Uppers
One thing that I need in my athletic shoes is ankle support. Cross trainers usually have mid-tops that provide a degree of ankle support without the restrictiveness of high top shoes. Most uppers are made from leather, along with synthetic mesh. The leather offers stability, while the mesh provides breathability, so that there isn't a problem with your feet becoming uncomfortable from the moisture.
Another thing that many cross trainers come with is a lacing system that is secure. This provides additional stability and ankle support, especially for side to side movements.
