A crutch comprising an axillary support, an upper shaft segment having a first end and a second end, an intermediate shaft segment having a first end and a second end, and a lower shaft segment having a first end and a second end;
- said axillary support connected to the first end of said upper shaft segment at a first angle of between approximately 10 and 15 degrees;
- the second end of said upper shaft segment connected to the first end of said intermediate shaft segment at a second angle of between approximately 15 to 20 degrees outward in the same plane as the first angle and approximately 15 to 20 degrees forward in a plane orthogonal to the plane of said first angle;
- the second end of said intermediate shaft segment connected to the first end of the lower shaft segment at a third angle of between approximately 20 to 30 degrees outward in a plane orthogonal to the plane of said second angle.
