Provided is a crutch that may be collapsed for storage and shipment, adjustable for different users and mitigates the affect of the enrich striking the ground. A saddle support surface is coupled to two rails that extend and slide through a handrail and a wishbone. The rails may be secured with respect to the handrail and wishbone in a variety of positions, enabling the distance between the support surface and the handgrip and the length of the crutch to be adjusted. In addition, the rails may be positioned in the handrail and wishbone such that the support surface fits against the handrail and the handrail against the wishbone. A shock tube extends from and slides through the wishbone and may be secured in a variety of positions to adjust the length of the crutch to account for different users and to minimize the length for storage and shipment.
