Trail shoes offer increased outsole traction, midsoles similar to those of stability shoes and uppers with toe bumpers and reinforced stitching for more durability. When you loot at the imprint, you should be able to classify your foot types in to one of three common foot types. Normal feet have a normal-sized arch and leave an imprint that has a flare but shows the forefoot and heel connected by a wide band. Runners with a normal foot and normal weight are usually considered biomechanically efficient and don't require motion-control shoes. Stability shoes with moderate control features such as a two-density midsole.
Flat feet have a low arch and leave a nearly complete imprint.
That is, the imprint looks like the whole sole of the foot. Over time, this can cause many different kinds of overuse injuries. Straight or semicurved. Motion-control shoes, or stability shoes with firm midsoles and control features that reduce the degree of pronation. Stay away from highly cushioned, curved-lasted shoes that lack stability and control.
