What Are Split Running Shorts

When it comes to running gear, one essential item that every serious runner should consider is a good pair of split running shorts. These shorts are a popular choice among athletes and fitness enthusiasts because of their unique design and functionality. In this article, I will dive deep into what split running shorts are, how they differ from other types of running shorts, and why they are my personal favorite choice for running.

What are split running shorts?

Split running shorts are designed with a high cut on the sides, allowing for maximum freedom of movement and ventilation. Unlike traditional running shorts, which typically have a more relaxed fit, split shorts have a more streamlined and lightweight construction.

The main feature of split running shorts is the slit on the sides, which extends up to the upper thigh or hip area. This design allows for a greater range of motion, which is especially beneficial for runners who engage in high-intensity workouts, sprints, or long-distance runs.

How do split running shorts differ from other types of running shorts?

While split running shorts may look similar to other types of running shorts at first glance, there are a few key differences that set them apart:

  1. Split design: As mentioned earlier, the defining feature of split running shorts is the high-cut sides, which provide optimal freedom of movement. This design element allows runners to move their legs more freely, reducing the risk of chafing and improving overall comfort.
  2. Lightweight construction: Split running shorts are typically made from lightweight, moisture-wicking materials such as nylon or polyester. This ensures that the shorts stay dry and lightweight, even during intense workouts or in hot weather conditions.
  3. Brief liner: Another feature that sets split running shorts apart is the built-in brief liner. This liner provides support and helps to prevent any unwanted movement or discomfort while running. It also adds an extra layer of protection against chafing.

Why are split running shorts my personal favorite?

As an avid runner myself, split running shorts have become my go-to choice for several reasons:

  • Freedom of movement: The high-cut sides of split running shorts allow my legs to move freely and without any restrictions, which is essential for maintaining a proper running form and maximizing speed and efficiency.
  • Ventilation: The split design of these shorts provides excellent ventilation, keeping me cool and comfortable during long runs or intense workouts. The lightweight materials also help to wick away sweat, further enhancing breathability.
  • Comfort: The built-in brief liner provides added support and prevents any discomfort or chafing. Additionally, the lightweight construction of split running shorts feels barely noticeable, allowing me to focus more on my run without any distractions.
  • Performance: The combination of freedom of movement, ventilation, and comfort offered by split running shorts ultimately translates into better performance for me. I feel more agile and confident while wearing them, which helps me push myself to achieve my running goals.


Split running shorts are a fantastic choice for runners who value freedom of movement, ventilation, and overall comfort. Whether you’re an experienced marathon runner or just starting your fitness journey, investing in a good pair of split running shorts can greatly enhance your running experience. Give them a try, and you’ll see why they have become my personal favorite running gear.
