Low-profile Design
The boot design of the Quatro has been modified to reduce the coverage around the mid-foot and allow for unrestricted plantar flexion.
Stirrup & Stabilizing Straps
Internal stirrup strap travels through slots in the dynamic cuff and continues outside the boot to form the stabilizing straps. This patented design better captures the calcaneus (heel) and resists inversion or eversion of the ankle to help stabilize the talocrural and subtalar joints.
Dynamic Cuff
Ultra thin plastic cuff works in concert with strapping system to provide circumferential compression around the distal tibiofibular joint. In addition, the dynamic cuff is now lined with CoolFlex™ padding for improved comfort and Skinloc™ material to resist distal migration.
