Cramer® Dorsal Night Splint Active Ankle's DNS prevents passive plantar flexion instead of active dorsiflexion in other night splints that can be uncomfortable. The splint can be worn on either the right or left foot and is designed with an anti-slip pad on the bottom for safe nighttime ambulation. The unique clamshell design is triple-stitched and includes a stretch resistant strap for exceptional support. Patients are willing to wear the boot for longer periods of time because it is lightweight and easy to wear. Only part of the leg and foot are actually strapped in the boot, leaving the heel, calf, and toes open. This eliminates the area from overheating and gives the patient more freedom to move with the splint.
