Hey wanted to give you feedback. I am a walking ad for DonJoy! I've been to 3 elite lacrosse tournaments and I wear the Trizone cuz I walk and stand all day. I've had a handful of people at each one ask about it! I've been wearing the reaction one too when I run. Everyone that asks me I point them to your site. Anything else I can do to get a better word out there. I really have had a lot of people ask. You know we only "hang" with the sporty over 40 and they all have knee probs!!! Glad I have DJ stuff cuz it really does help. I'm not sore at night like I usually am.

I have had two major injuries during my career—both ACL tears. There is a lot of pressure inside and outside of schools and organizations to recover quickly, which I appreciate, but it’s up to young athletes, parents and coaches to take steps to recover safely and guard against injury and re-injury. This will only allow for a stronger, better return to sport in the long run.

Do love this brace. I have worn TriZone for 3 races and won my age group in each race. My knee is fine, no problems, it’s the best brace I’ve ever had.
