At fist glance you can tell the difference between waterproof running shoes built for the trails and a regular runners. These shoes look very aggressive and ready to crush rocks, kick up dust, and hike through water. When looking at waterproof trail running shoes I tend to think of a off road truck or monster truck where normal runners are your plain everyday suv’s or sedans.
Waterproof running shoes designed for the trails are created with aggressive tread designs that help to cling to the terrain better than normal running shoes. The soles of these shoes are also heavier than non-trail shoes. This section of the shoe is also known as the outsole. The thicker sole makes the shoe not as flexible as a traditional runner. So if you have never worn trail shoes before this is something you may have to get use to. But like anything else you will get accustom to it over time.
The midsole is the part of the shoe that focuses on the comfortability of the shoe. This part is positioned just above the outsole of the shoe, and covers the entire length. Stability, flexibility, and durability all play a huge factor in the construction of this part of the shoe.
The insole sets right above the midsole and below your foot. This is another section that helps to create the comfort of a shoe. The insole aids in helping to control foot motion and stability. In most cases these insoles can be removed and replaced. Other terms for insoles are called footbeds or innersoles.
