Abstract
A shoe sole (6) provided with a number of rigid spikes or nails (12) on its face in contact with the ground, said spikes or nails being not fixedly secured to the sole but being able to pass from a first extracted position in contact with the ground to a second retracted position not interfering with the trampling surface because of the combination of folding spike support means which can be overturned with first and second grooves or recesses (20) formed in the sole within which such spike support means can be accommodated in the extracted and the rest positions.
