Standard crutches are hard on the body and haven't changed much over the course of history. The last major innovation was revising the basic "T" shape to the now ubiquitous adjustable A-frame—and that was during World War II. Mobilegs takes the design to the 21st century with modern materials and careful attention to ergonomic factors (which should come as no surprise given that their inventor helped design the Aeron chair). The new design provides better stability and reduces the type of secondary injuries—like nerve damage and wrist strain—associated with its predecessors. Better still, the lightweight crutches cost the same as the standard set.
