The airiness is in the top first criteria for you to choose the best walking shoes because whether the shoes are airy and cool or not can affect significantly your practice. The shoesâ€™ material is the most important factor in deciding if the shoes can cause the difficulties when training or not. Some shoe brands use the modern technology to create the small and knitted holes to make the airiness more effective. If you choose the too thick shoes having many pads, they will protect your feet better but reduce the airiness. Thus, you should set the priority for the airiness to choose the appropriate shoes yourself.
