A sole structure for a shoe, comprising:

• a forefoot portion;
• a heel portion;
• a midfoot portion coupled to the forefoot portion and the heel portion, the midfoot portion comprising a plurality of connectors disposed on a ground-facing side of the midfoot portion, the plurality of connectors comprising a first connector and a second connector, the first connector located closer to the forefoot portion than the second connector;
• and
• a resilient component coupled to the first connector and the second connector,
• wherein the midfoot portion has a resting state in which the resilient component has a first length,
• wherein, when the midfoot portion bends in a dorsiflexion direction, the first connector and the second connector move away from each other and pull the resilient component to a second length longer than the first length, and
• wherein, when the midfoot portion bends in a plantarflexion direction, the first connector and the second connector move toward each other and allow the resilient component to relax to a third length shorter than the first length.
