Running, It's Good for You
There are many benefits to running. These benefits include decrease in blood pressure and body weight, and increase in lung capacity.
Equipment for running is minimal however a good pair of running shoes is a must. Running shoes provide substantial midsole foot cushioning, arch support, aid in prevention injuries, and can promote improved athletic performance.
Arch support is very important especially in individuals with flat feet. Midsole cushioning can ease the stress put on the heels, ankles, and toes during a run. A good pair of running shoes can prevent injuries such as tendonitis, stress fractures, and joint pain.
Improvement in your performance may also occur because of greater comfort and improved running capacity.
This being said I would go out and find a great pair of running shoes to help with your performance. Especially if they help to reduce the risk of injuries while running. Running shoes are important, especially if you run multiple times a week and long distances.
