Do they fit with motocross boots? Do they have any ACL support?
Josh Peacock - February 21, 2019
Thank you for your inquiry Josh. Yes, they do fit inside any motocross boot. These Leatt X-Frame Knee Braces are a hinged knee brace with a high level of support. If you have a mild ACL/LCL/MCL instability such as a partial ACL tear, this type of ACL brace for knee support can prevent further damage while enabling the user to participate in contact or non-contact sports. -- Kyle & the Chap Moto Team
