Question: Anyone that had used this for soccer? how comfortable it is? thank you.
Document: These knee support braces have worked wonders for me! I had gotten to the point because of ligament damage and arthritis I could hardly walk anymore. I was getting steroid injections on my knees every 2 or 3 months. With these braces I haven't needed anymore injection, can walk and even ride my mountain bike. The person who gave this product one star review because they ordered the wrong size is ridiculous.
I ordered 2XL but it doesn't fit my knee at all. I tried to give it to friends who are much thinner but it also didn't fit their knees.
Answer: no
