The invention provides a double-layer shockproof sole, which comprises an outsole and a midsole. The double-layer shockproof sole is characterized in that double-layer elastic shockproof pads are arranged on the midsole and at least distributed in the front and the rear of the midsole, the upper elastic shockproof pad is provided with a first upward protrusion, the lower elastic shockproof pad is provided with a second downward protrusion, and the first upward hollow protrusion and the second downward hollow protrusion are arranged oppositely so that an inner cavity of the first protrusion is opposite to an inner cavity of the second protrusion. The double-layer shockproof sole has excellent shock proofing effect, thinner positions of the sole such as the front and the like are capable of structural shock proofing, movement impact and fatigue can be relieved effectively, sport injury is avoided, movement stability of the sole is unaffected, movement starting force can be increased, walking or sports are easier, and vitality is multiplied.
