How to Know if My Compression Socks Are Too Small?

Compression socks are widely used for their therapeutic benefits, especially in managing conditions like varicose veins, deep vein thrombosis (DVT), edema, and poor circulation. They apply controlled pressure to the legs, helping to improve blood flow and reduce swelling. However, wearing the wrong size of compression socks can lead to discomfort or, worse, exacerbate the very issues they are meant to solve. Understanding how to know if your compression socks are too small is essential to ensure maximum comfort and effectiveness.

Understanding Compression Socks and Their Fit

Compression socks come in different sizes and compression levels, typically measured in mmHg (millimeters of mercury). The higher the mmHg, the greater the compression the socks provide. For example, socks with a compression level of 8-15 mmHg are generally considered mild compression, while 15-20 mmHg provides moderate compression, and 20-30 mmHg is high compression.

When choosing compression socks, it is crucial to get the correct fit. A sock that is too small can cause more harm than good, restricting circulation and causing pain or discomfort. On the other hand, a sock that is too large may not provide the intended level of compression.

Signs That Your Compression Socks Are Too Small

Excessive Tightness or Discomfort

One of the most immediate signs that compression socks are too small is a feeling of excessive tightness or discomfort. Compression socks are designed to apply pressure to the legs, but they should not feel painfully tight. If the socks dig into your skin, cause discomfort around your calf, ankle, or knee, or leave deep indentations, it’s a clear indication that the socks may be too small.

This discomfort is especially important to monitor if you're wearing socks like the JOBST forMen Compression Socks 8-15 mmHg Knee High Closed Toe or the mediven active 15-20 mmHg calf closed toe standard. While these compression levels are designed for mild to moderate support, they should not feel tight to the point of discomfort. If they do, you may need to move up to a larger size.

Skin Marks and Indentations

Another telltale sign that your compression socks are too small is the appearance of skin marks or indentations after you take them off. Compression socks are meant to fit snugly without causing a painful or restrictive fit. However, if you notice that the socks leave deep lines or indentations on your legs, it could indicate that the socks are too tight, leading to constricted circulation.

For instance, the JOBST forMen Casual Compression Socks 20-30 mmHg Knee High Closed Toe provide higher compression than the 8-15 mmHg version. If these leave noticeable marks or cause pain around your calf or ankle area, this is a strong indication that they may be too small, and you should consider a different size.

Swelling or Numbness

Compression socks are designed to help alleviate swelling, not cause it. If you notice that your feet, ankles, or calves are more swollen after wearing compression socks, this could be a sign that they are too tight. Additionally, numbness or tingling sensations are a red flag. Compression socks should improve circulation, but if they are too small, they may impede blood flow, causing these unwanted symptoms.

Shortness of Breath or Leg Fatigue

In more extreme cases, if compression socks are too small, they can cause a feeling of shortness of breath or leg fatigue. Compression socks are designed to relieve pressure from the feet and legs, but improperly sized socks may actually restrict blood flow, making your legs feel more fatigued or causing a feeling of tightness in your chest due to restricted circulation.

If you are experiencing these symptoms, especially when wearing higher compression socks like the JOBST forMen Casual Compression Socks 20-30 mmHg Knee High Closed Toe, you should reconsider your fit and possibly move to a larger size or a different compression level.

How to Properly Measure for Compression Socks

To avoid the discomfort of wearing socks that are too small, it’s essential to measure your legs correctly. Follow these steps to ensure a proper fit:

  1. Measure your ankle circumference: Measure around the narrowest part of your ankle. This is where the compression should begin.
  2. Measure your calf circumference: Measure the widest part of your calf.
  3. Measure the length of your leg: For knee-high compression socks, measure from the floor to the bend of your knee.

Using these measurements, refer to the sizing chart provided by the manufacturer of the compression socks. Brands like JOBST and mediven provide detailed sizing guides to help you find the right fit. Dunn Medical offers these brands and can assist with choosing the appropriate size based on your measurements.


Final Thoughts 

Compression socks are an excellent tool for improving circulation and relieving conditions like swelling, varicose veins, and fatigue. However, wearing socks that are too small can cause more harm than good, leading to discomfort, skin marks, or restricted blood flow. To ensure you are getting the most out of your compression socks, it is important to measure your legs properly and choose the correct size and compression level.
