But first, do you even need knee sleeves? Consider:

The answer is likely yes to both of these, meaning knee sleeves might be a good idea. Just remember that knee sleeves are not a substitute for a knee brace. Also consider:

  • Do you experience knee pain or discomfort during workouts?
  • Have you had- or do you currently have- tendonitis in your knees?

While knee sleeves may help, serious or chronic knee pain, certain issues might warrant alternative solutions.

Now, let’s take a look at how (and which kind of) knee sleeves can up your CrossFit game in 2018.

What Are Knee Sleeves?

Think of knee sleeves as a hug for your knee joint.

They add compression to your knees as you exercise, helping your knees function the way they are meant to.

The right pair can provide compression, warmth and stability during heavy lifts and workouts.

CrossFit requires their athletes to have strong, functioning knees for most movements. You’d be hard-pressed to come up with a good WOD that doesn’t put stress on your knees.

Over time, all of those squats, dips, lunges, and steps can take a toll. One way to decrease the stress on your knees is to wear knee sleeves.

The wrong pair of knee sleeves can get destroyed in only a few workouts.

Worse, they can limit mobility and decrease performance when you use them.

Why Use Knee Sleeves?

Because of the nature of CrossFit, knee sleeves could be useful to you in one or more settings at your local box.

You might use them during heavy lifts, for certain movements in WODs, or to simply keep your knees warm and fluid when you train.

CrossFit athletes will likely benefit the most from knee sleeves that are both supportive and versatile.

If you plan to use them for WODs, you’ll want a pair that is strong enough to stabilize during heavy squats, but flexible enough to not feel constricting when running or rowing.

But why use them in the first place? For example, consider how often a CrossFit athlete might squat in a week.

Take a given week of Monday’s heavy back squat session, Wednesday’s AMRAP with thrusters, and Saturday’s air squat assault.

In all, that week of programming contains somewhere between 300-500 squats. That’s a lot of work on your knees.

Knee sleeves will keep your knees warm and stable while you work out, limiting injuries and keeping you feeling healthy.

Two benefits of any good pair of knee sleeves include:


The compression that your knee sleeves offer will keep your knees stable when squatting or performing other CrossFit movements.

This will decrease your chance of knee injury and allow you to perform better when doing heavier, more explosive lifts.

Joint Warmth

Whether you are performing a 3RM squat or warming up with a PVC pipe, cold joints never feel good.

Good knee sleeves will increase blood flow to your knees and keep them your knees warm throughout your workout, helping you to be more fluid and powerful with your movements.

Is knee warmth a priority for you? Here are a few knee sleeve recommendations that will ensure you’re taken care of:

How are Knee Sleeves for CrossFit Different From Lifting Knee Sleeves?

Although there are various similiarties between knee sleeves designed for CrossFit and those aimed at weight lifters there are certain key differences you should be aware of.

Firstly, Knee sleeves for CrossFit are built to offer more stability to your knee joint and provide support, this is exactly the same of knee seeleves designed for weight lifting.

The main difference is that lifting knee sleeves are created to be even tighter and offer additional compression around the knees.

Quite simply, knee sleeves aimed at CrossFit atheletes are often not as ‘tight’ as those that are choosen to be worn by weight lifters.

CrossFit workouts don’t require the level of lifting that weight lifters will often carry out during their training sessions as a result knee compression isn’t such a high priority for CrossFit.

Weight lifters will oftern choose to where knee wraps to provide an even tighter fit because many knee sleeves, although they offer support, just aren’t going to fit as tightly around the knee joints as a wrap can.

Things To Consider When Buying Knee Sleeves

So now you know what knee sleeves are, and how they’ll help you. You know they should be supportive, but not constricting.

You’re ready to buy, right?

Hold on. There’s a few other factors to consider first to make sure you are buying the right pair of knee sleeves for you and your fitness goals.


When you start shopping around, you’ll learn that you must choose the thickness of your knee sleeves.

Here is a brief description on the three measurements you are most likely to come across.

  • 3mm– Ideal for endurance workouts or endurance athletes.
  • 5mm– Ideal for mixed activities, like a WOD in CrossFit or any other type of cross training.
  • 7mm– Ideal for heavy lifting or any movement that requires heavy stabilization.

For more details, check out this guide for picking the right knee sleeve thickness.


It’s important to consider the material of your knee sleeves, because each material will provide a different feel and different benefits.

For example, if you only need them for heavy squats, you’ll want a pair that offers less flexibility and more stability.

Here is a brief description of the materials you will find:

  • Cloth offers light support and joint warmth. Cloth will likely wear down quicker than others with high volume exercise, but will endure basic lifting.
  • Neoprene – versatile, supportive, medium level of thickness. Generally speaking, neoprene material is probably your best bet for CrossFit workouts.
  • Knee Wrapsadjustable, supportive, but not always stable during workouts with variety. Good for warming up joints prior to a workout or heavy lifts.

Consider what you’ll need your knee sleeves for. While neoprene sleeves will likely work best, they are usually the most expensive.

If you only need your knee sleeves for lifting, you might not need them!

Gym Pro Tip: Know that neoprene sleeves tend to acquire an almost legendary odor after a few months of use. For your nose, and the noses of other gym-goers, be sure to wash your knee sleeves every few weeks.


Mobility comes down to personal preference. Some people enjoy the mildly constricting feeling of a thick knee sleeve, ensuring their joints are supported.

Others prefer the joint warming benefits of a light sleeve and don’t like the sensation of limited mobility.

The best way to find your preference is to experiment.

Practice different movements and see what feels good. See what might decrease performance or feel like a pestilence.
