I can’t recommend this brace highly enough. Due to a disc herniation and nerve damage my left heel was dropping til my ankle clashed on every root. 661’s (sprained ankle) brace gives the wrong kind of support for my issue.
Dynamic tape (very springy) helped me, but this brace really solved the problem.
It’s not designed for my purpose, but for those hard descents where continuous rocks or roots (or alpine rain grooves) cause sometimes very painful front of ankle clash. And for big “cases” off jumps, of course, for those mad enough to try such.
Hence the name.

“Designed for those moments when you case a landing hard and your feet reach Maximum Dorsiflexion (Foot Upward Flexion). ‘ANTI CASE ANKL’ braces you when you need the support on hard hits and is flexible when you need to control and finesse your bike.”
I’ve added a few comments to the end of the Pinkbike article. As you can tell I’m very grateful for the invention.
