Hello Sir,

Thank you so much for writing in with your feedback. I understand you have some trouble with the sizing of the knee brace. I am sharing a link which would help you determine if the size you have is the right size. Please ensure you measure your thigh 8cm above your knee for sizing.

As with any elastic material, the knee brace will loosen slightly upon repeated use - please factor that in as well when making your selection.  We will be happy to exchange the product to give you the right size (as long as the product is is saleable condition). If you feel that there is a manufacturing defect, please visit the nearest store for our teammates to check the product.

In case of any further questions / feedback, please do not hesitate to reach us on

Thanks and regards,

Hello Malek

We are glad that you are satisfied with the product.

Your review would mean so much to our future customers who are looking into getting a back brace.

The size range is not helpful and is not directly related to waiste size. As it's important to significantly overlap both ends go up one size. Mine is unusable as it's too small for a 32"waiste.

Hello Michael,

thanks for taking the time to leave a review on the Soft 300 Lumbar Brace.

I'm sorry to hear about your not satisfactory experience with our supports sizing unfortunately, being a international company, we had to come up with a sizing system that could work for all of our customers so, for all of our supports, there are specific measurements that need to be taken to understand which size would fit properly.

Anyway, I can suggest you to take the item with the receipt to the closest Decathlon store where you can exchange it for the right size or get a full refund.



Lumbar support

Give proper support.

Fits a bit larger than suggested

The fit is a bit larger than the sizing indicates on the packaging. Go down one size for a better fit in my opinion.

Dear Gerald,
Thank you for your time to write this review for us.
I hope you like the usage of the product and hope it's comfortable to you.
For the sizing because we have produced for mass production sometimes it might not fit for some people, we will develop the accuracy of the measurement in the future for a better choice for you and another users.

Why wear this back brace?

Wearing this back support, with its boning at the back, may be recommended if you have lower back pain/lumbago, or if you are unsure about how your back will cope when getting back into sport (basketball, soccer, handball, tennis, running, trail running, gymnastics, judo). It is easy to put on and adjust, with a shape designed to fit your back and keep you comfy.

What is the difference between lower back pain and lumbago?

Lower back pain and lumbago are actually the same thing: back pain in the lumbar region. This pain can be caused by different things, from fractures to deformities and slipped discs. The pain will only disappear if the cause is treated. Wearing a back brace can help reduce pain thanks to its heating action, compression, and the restricted movement.

Choosing your lumbar brace size

Measure your waist size, to 2" above the hips. Then match the measurement taken with the following size chart: Size 1: 25.6" - 33.5" Size 2: 33.5" - 45.3" Size 3: 45.3" - 55.1"
