Types of Wear Patterns
Heel Strike Pattern
The heel strike pattern is characterized by excessive wear on the outer edge of the heel of your running shoes. This type of wear pattern is common among runners who have a heel strike running style, which means that they land their heel first when their foot makes contact with the ground. When your heel strikes the ground with significant force, it results in the outer edge of the heel wearing down quickly. If you notice this wear pattern on your shoes, it may indicate that you are a heel striker and may benefit from shoes that provide extra cushioning in the heel area.
Toe Off Pattern
The toe off pattern, as the name suggests, refers to excessive wear on the toe area of the outsole. This wear pattern is typically seen in runners who have a toe-off running style, meaning they push off the ground with their toes to propel themselves forward. As you push off forcefully with your toes, the front part of your shoe sole experiences increased pressure and friction, leading to wear on the toe area. If you observe this wear pattern on your shoes, it may indicate that you have a toe-off running style and could benefit from shoes with reinforced toe areas for added durability.
Medial and Lateral Patterns
The medial and lateral wear patterns are characterized by wear on the inner (medial) or outer (lateral) edges of the shoe sole, extending from the heel to the toe. These patterns are often seen in runners with pronation or supination issues. Pronation refers to the inward rolling motion of the foot during the foot strike and push-off phases, while supination is the outward rolling motion. Excessive pronation can lead to wear on the inner edge, while excessive supination can result in wear on the outer edge of the shoe sole. If you notice these wear patterns on your shoes, it might be an indication that you need shoes with proper support and stability features to help correct your running gait.
Running Surface
Asphalt
Running on asphalt surfaces can put significant stress on your running shoes’ soles due to its hard and unforgiving nature.
