The Nike Air Max shoes were retroed as par of the History of Air pack and was also made available on NikeiD where one could make their own custom Nike Air Max shoes.The high tech material is not only waterproof,but it is also breathable which is a GREAT combination for runners.Traditionally,runners would need to make a sacrifice for either a breathable shoe or one that is waterproof.In fact,most hardcore runners have several shoes specifically for what the weather is like outside.Now runners could instead by the Nike Air Max 2003 and have all they need in one shoe.
