An adjustable spring device for walking and running is attached to user's footwear creating comfortable conditions during the locomotion. In an embodiment, it includes: an upper lever and lower lever locating one above the other, wherein at least one of the levers is made of elastic material, and a support mechanism having a joint shaft that allows the levers to be pivoting. The device includes a first flexible link connecting the front ends of the levers, and a second flexible link connecting the rear ends of the levers. The links can be adjusted to a certain constant length before the deployment of the device. For creating optimal energy exchange conditions between the device and user, and reducing the shock loads on the user's leg joints and spine, the device can be adapted by shifting the support mechanism between the levers and by adjusting the flexible links between the lever ends.
