What is the Best Underwear for Running?

Running is an excellent form of exercise that offers countless physical and mental health benefits. However, it can also come with its fair share of discomforts, particularly when it comes to choosing the right underwear. In this article, we'll discuss the importance of selecting the right running underwear, explore different types of running underwear, and introduce SOMI Apparel Thongkillers, a fantastic option for women seeking comfort and performance.

Why Underwear Matters for Running


Comfort is a top priority for runners, as it can significantly impact your overall experience. Ill-fitting or uncomfortable underwear can lead to chafing, irritation, and general discomfort, which can hinder your performance or even discourage you from running altogether.

Moisture Management

Sweat is inevitable when you're running, and proper moisture management is crucial to staying comfortable and avoiding irritation. The right running underwear should wick sweat away from your skin, helping you feel dry and fresh throughout your run.

Reduced Chafing

Chafing is a common issue for runners, caused by repetitive friction between your skin and clothing. Quality running underwear should minimize chafing by providing a smooth, seamless fit that reduces friction and irritation.

Types of Running Underwear


Briefs offer a traditional fit and coverage, sitting low on the hips and providing minimal fabric on the sides. They can be a comfortable option for runners who prefer a classic underwear style.

Boxer Briefs

Boxer briefs offer a longer leg length than briefs, providing extra coverage and support. They can be ideal for runners who experience chafing on the inner thighs or prefer additional support during their runs.

Compression Shorts

Compression shorts are designed to provide muscle support and improve circulation. They often feature moisture-wicking materials and a snug fit, making them a popular choice for many runners.


Thongs provide minimal coverage and eliminate visible panty lines, making them a popular choice for those who prefer a barely-there feel. However, not all thongs are suitable for running, as some can cause chafing or discomfort.

How to Choose the Right Running Underwear

When selecting the perfect running underwear, it's essential to consider the following factors:


Choose a moisture-wicking material like Sustainluxe to keep you dry and comfortable during your run. Avoid materials like cotton, which can absorb sweat and lead to chafing or irritation.


The right fit is crucial for reducing chafing and ensuring comfort. Look for underwear with a snug, seamless fit that doesn't bunch or ride up during your run.

Personal Preferences

Your personal preferences will also play a significant role in determining the best running underwear for you.


Choose a style that suits your needs and preferences, whether it's a brief, boxer brief, compression short, or thong. Consider the benefits and drawbacks of each style and how they align with your running habits and comfort level.


Quality running underwear can be an investment, but it's often worth spending a bit more for a product that will provide lasting comfort and performance. Evaluate your budget and consider the long-term value of your purchase.
