The Zamst ZK-7 is third because it is built for one clear job, protecting knee ligaments in sport, and documents how it does it. Zamst lists it for moderate to severe sprains of the ACL, MCL and LCL and for sports that need ligament protection, including volleyball, basketball, soccer and skiing. Resin stays limit excessive side-to-side movement without restricting the range of motion, while an X strap and parallel straps limit forward movement of the knee. A semi-open front panel lets you adjust the fit on the lower leg, and the rear uses a breathable mesh. It comes in 7 sizes from Small to 4X-Large, and Zamst ships standard orders free. At $56.99 on sale it is close to the Shock Doctor Ultra, but its regular price is $79.99, it uses resin stays instead of metal hinges, and the store page shows only 9 reviews so far.
