1. A crutch having a first side direction generally parallel to a walking direction of a user, a second side direction opposite the first side direction, a third side direction perpendicular to the first side direction and a fourth side direction opposite the third side direction, comprising: a saddle, extending in an elongate shape between the first side direction and the second side direction, the saddle including— a frame having a support membrane disposed on the frame, the frame and the support membrane providing: an inner lobe configured to rest against a torso of the user during use,an outer lobe configured to rest against an arm of the user during use, anda top portion connecting the inner lobe and the outer lobe and forming a U-shaped channel having an curved upper surface configured to fit within an armpit of the user with the U-shaped channel open along at least a portion of a downward facing side;a pivoting joint attached to the frame; anda spring mechanism having an upper portion attached to the pivoting joint such that the joint is configured to allow the spring mechanism to move with respect to the frame along an arced path; andan elongate leg removably attached to the spring mechanism of the saddle at a top end of the elongate leg, the elongate leg extending downward from the saddle toward a bottom end of the elongate leg during use;wherein the saddle remains generally stationary in the armpit of the user and the elongate leg pivots in response to the user manipulating the crutch in the walking direction. 2. The crutch of claim 1, wherein the joint includes a pin on which the elongate leg pivots in a direction generally parallel to the first side direction. 3. The crutch of claim 1, wherein the joint is a ball-and-socket joint enabling the elongate leg to pivot along the arced path generally parallel to the first side direction extending laterally away from the user in the third side direction or fourth side direction at a central portion of the arced path. 4. The crutch of claim 1 wherein the frame and the support member comprises a resilient mat such that the frame and the support member can expand in the third side direction and fourth side direction and contract vertically under the weight of the user. 5. The crutch of claim 1, wherein the spring mechanism includes a spring that is at least partially compressed by the spring mechanism regardless of a load on the crutch. 6. The crutch of claim 5, wherein the elongate leg further comprises, a vertical slot, the vertical slot having a top end; and the spring mechanism further comprises a pin arranged to protrude at least partially into the vertical slot; andwherein the spring biases the pin toward the top end of the vertical slot. 7. The crutch of claim 1, further comprising handle including a fixed end attached to the elongate leg and a free end extending away from the elongate leg; and wherein the handle is cantilevered up such that when an axis extending between the top end of the elongate leg and the bottom end of the elongate leg is vertical, the free end of the handle is higher than the fixed end of the handle. 8. The crotch of claim 7, wherein the handle is repositionable along a middle portion of the elongate leg. 9. A crutch having a front side facing in a walking direction of a user during use, aback side opposite the front side, an inner side facing toward the torso of the user, and an outer side opposite the inner side, the crutch comprising: a saddle extending in an elongate shape along an axis from the front side to the back side, the saddle including— a frame having a support membrane disposed on the frame, the frame and the support membrane providing: an inner lobe configured to rest against a torso of the user during use,an outer lobe configured to rest against an arm of the user during use, anda top portion connecting the inner lobe and the outer lobe and forming a U-shaped channel having an curved upper surface configured to fit within an armpit of the user with the U-shaped channel open along at least a portion of a downward facing side;a pivoting joint attached to the frame; anda spring mechanism having an upper portion attached to the pivoting joint such that the pivoting joint is configured to allow the spring mechanism to move with respect to the frame along an arced path; andan elongate leg removably attached to the spring mechanism of the saddle at a top end of the elongate leg, the elongate leg extending downward from the saddle toward a bottom end of the elongate leg during use; anda foot disposed at the bottom end of the elongate leg;wherein the saddle remains generally stationary in the armpit of the user and the elongate leg pivots in response to the user manipulating the crutch in the walking direction. 10. The crutch of claim 9 wherein the joint includes a pin on which the elongate leg pivots along a path generally parallel to the path between the front side and the back side during use. 11. The crutch of claim 9, wherein the joint is a hall-and-socket joint enabling the elongate leg to pivot along the arced path during use, at least a portion of the arced path extending in the direction of the outer side. 12. The crutch of claim 9 wherein the frame member comprises a resilient material, such that the frame member can widen along an axis from the front side to the back side and contract vertically under the weight of the user. 13. The crutch of claim 9, wherein: the spring is at least partially compressed by the spring mechanism regardless of a load on the crutch;the elongate leg further comprises a vertical slot, the vertical slot having a top end;the spring mechanism further comprises a pin arranged to protrude at least partially into the vertical slot; and whereinthe spring biases the pin toward the top end of the vertical slot. 14. The crutch of claim 9, further comprising a handle including a fixed end attached to the elongate leg and a free end extending, away from the elongate leg; and wherein the handle is cantilevered up such that when an axis extending between the top end of the elongate leg and the bottom end of the elongate leg, is vertical, the free end of the handle is higher than the fixed end of the handle. 15. The crutch of claim 14, wherein the handle is repositionable along a middle portion of the elongate leg. 16. A method of use of a crutch by a user having a front side and a back side, the crutch including a saddle, an elongate leg, and a handle; the saddle including a frame having a support membrane disposed on the frame, the frame and the support membrane providing: an inner lobe, an outer lobe, and a curved top portion connecting the inner lobe and the outer lobe and forming a U-shaped channel open along at least a portion of a downward facing side, a pivoting joint attached to the frame; and a spring mechanism having an upper portion attached to the pivoting joint such that the pivoting joint is configured to allow the spring mechanism to move with respect to the frame along an arced path; the elongate leg removably attached to the spring mechanism of the saddle at a top end of the elongate leg, the elongate leg extending downward from the saddle toward a bottom end of the elongate leg during use; and the handle operably coupled to the elongate leg at a point between the top end and the bottom end; the method comprising: arranging the saddle in an armpit of the user, such that— the saddle extends an in elongate shape along an axis between the front side and the back side,the inner lobe rests against the torso of the user, andthe outer lobe rests against the arm of the user;grasping the handle with the hand of the user con the same side as the armpit;stepping forward with the foot of the user opposite the armpit while transferring at least a portion of the weight of the user to the crutch via the saddle;transferring at least a portion at the weight of the user to the that while pivoting the elongate leg between the back side and the front side;such that the saddle remains generally stationary in the armpit of the user as the user steps forward.
