Purchasing anything new can be a lot of fun, but it can also be very frustrating. Purchasing a pair of Running shoes is no different, and do the nature of our bodies I wouldnt recommend rushing into a pair of shoes just because they are cheap or convenient.
No two people have exactly the same foot; however manufactures have divided shoes into three different categories: Cushioning, Stability, and Motion Control. Within these three categories their can be a lot of variation, but it is a good base guide to start with.
Cushioning – Cushioning shoes are shoes that have little to no lateral support. These shoes are good for runners who do not need this support, and have neutral feet. Generally this type of shoe will be for the runner with a high arch. Instances where this type of shoe is not right is in a case where you are a pronator or an overpronator.
Stability – Stability shoes are a mid range shoe category which offer a balance between cushioning and motion control. This shoe is for a runner who has a normal arch, lands on the outside of the foot and rolls forward. If you are unsure of where else to be this category is a good place to start....
