The present invention relates to the walking aid field. The present invention provides a walking aid, including a support frame, with a plurality of support legs disposed at a bottom of the support frame, and omni-directional wheels disposed on the support legs, wherein a buffering structure is further disposed between each support leg and each omni-directional wheel. In the walking aid provided by the present invention, a buffering structure is disposed between a support frame structure and an omni-directional wheel of the walking aid. On the one hand, the buffering structure may have a buffering effect in use of the entire walking aid, and when the walking aid contacts the ground, can act as a buffer to reduce physical energy consumption of a user in use of the walking aid, and lessen discomfort of the user as much as possible on the other hand, when the walking aid stops moving, the buffering structure can better support the walking aid securely on the ground, and when the walking aid stops, apply force downward to the walking aid, so that four effective contacts are formed by the casing of the buffering structure.
