Criteria Used for Evaluation

Size

The purpose of the knee sleeve is to make the run more comfortable and to facilitate a better performance. It’s there to protect against future injury and to provide support. All of this can be undermined if the sleeve does not fit properly. With the right amount of compression to the knee joint, circulation can be improved, speeding up the healing process and providing additional focus to that area. The wrong amount of compression can end up cutting off your circulation and having the opposite effect.

Before choosing a knee sleeve, try on one of comparable size. Make sure that it fits snugly, but that it’s not digging into your skin in a way that causes pain or makes it difficult to move. It can also help to measure the area surrounding your knee. A large sleeve is usually rated from 17 to 19 inches, a medium one is from 15 to 17 inches and a smaller one is 14 to 15 inches.

As we said before, you want the size to be slightly snug but not digging into the skin in a way that’s distracting or causing any additional injuries.

Materials

The material used for the knee sleeve should be both breathable and elastic. You also want it to be strong enough that it doesn’t stretch with time. This can result in the loss of support and add to the need to purchase a new one. A good product should be an investment in your health and not a bottomless money pit. Some knee sleeves can be fairly expensive and buying one a week because it’s poorly made just isn’t in the budget. If the material is too thick, it can lead to unnecessary sweating and slippage of the sleeve over time.

The thickness of the sleeves can be grouped into three major categories: 3 mm, 5 mm and 7 mm. The sleeves that are 3 mm thick are worn by marathon runners, they are able to provide stability and additional support during long runs. Weightlifters wear the 7 mm sleeves because they give additional support to the knees. The 5 mm sleeves happen to fit in all the other sporting activities, it is the universal knee sleeve for most athletes.

Knee Sleeve with 3mm thickness: Sports that need endurance
it's perfect for sports that need endurance like long-distance running. Athletes involved in such sporting activities use this type of knee sleeve cause it’s lighter. Hence making the sporting activity much easier. The sleeve provides support when the athlete starts to feel exhausted and weary by providing support towards the completion of the work out hence gaining control of one’s knee movements.

Knee Sleeve with 5mm thickness: For a mixed sporting activity
Ideally recommended for mixed sporting activities. Athletes who are involved in a variety of sporting activities that require a certain level of agility and extra support would find the 5 mm sleeve very helpful. The beauty of it is that it is used for a wide variety of sporting activities from track running to yoga fitness activities. It’s what many athletes would call a universal knee sleeve for all sporting activities.

Knee Sleeve 7mm thickness: For heavy but short activity
This type of sleeve calls for much heavier sporting activity but very short. It’s able to offer maximum stability to those athletes that are involved in heavy lifting. Extra support is provided during rehabilitation. The 7 mm sleeve has always been used by heavy lifters to provide additional support when lifting weights, though recently it’s been a favorite of people who work out in the gym and practice heavy lifting. It’s designed in a way that ensures the knee has maximum support for intensive but short sporting activities. Hence the exercises can be done more securely and precisely.

Durability

Durability is very important when looking for any sportswear. A good note was made of the material and how the stitching was done. This will determine how the sleeve will be able to stand up to the frequency of use. It's ok to pay less for a sleeve because expensive doesn’t always mean durable. But still, it’s good to play it smart when determining the durability of a knee sleeve. If you intend to have a high frequency in terms of the use of your knee sleeve, then you will definitely need something that is way durable.

This is especially true if an athlete is involved in a variety of sporting activities. If you do squats frequently every week, then you need a pair of knee sleeves that don’t rip after several uses. Knee sleeves that are found to be most durable are made of neoprene material, that is both flexible and soft. The cloth is also used cause it’s more breathable and has good stretching that is constant.

Comfort

Knee sleeves should not only provide support to your knees but then they should also be very comfortable. It’s important when shopping for a knee sleeve to look for one that won’t chafe your skin or make you feel itchy.

A comfortable fit is very important during your workout, even though it’s possible for the fit to affect the comfort of the knee sleeves. In order to make sure you attain both good fit and comfort, it’s important to look for a 3D design because this allows the knees to fit snuggly. The ergonomic knee sleeve has also been known to achieve a comfortable fit and to help support your body weight as you run.

Value

If money is no object, then go for the most expensive brands. There are budget-savvy knee sleeves brands that provide superior comfort, protection, and performance without the heavy price tag. If you got a budget then stick to it, remember expensive doesn’t always mean it will serve you best.
