There are so many choices and so many variations in shoes, types and needs that it occasionally becomes humorous thinking "I just need an average pair of running shoes".
How is anyone supposed to know what is the right running shoe when there are so many considerations? Well, here's a thing or two to verify if you have a normal type foot.
Your arch is probably an average height, which fundamentally means when your foot is wet, the yet foot print looks wide at the top, narrow in the middle, and not quite as wide as the top but bigger then the center part.
When you walk, your step rolls from the heal forward, the weight is slightly to the outside, or up the side of the foot.
If what was just mentioned is your foot, consider these characteristics and designs when buying your running shoes.
Look for words like 'good midsole support' or moderate, normal or average support in the sole.
You need a middle range type of all around support.
Lightweight is a general preference lately, with a combination of 'breathable fabric' and leather.
You may want to consider buying new socks and keeping them only for your running shoes as well.
It always provides a nice little pick-me-up.
