Patent ID: 7926205

Claim:
A sole arrangement, comprising: an upper sole member and a lower sole member, wherein the lower sole member is positioned closer to the ground during normal use of the sole arrangement, said lower sole member being movably attached to the upper sole member allowing the lower sole member to move in a vertical direction relative to the upper sole member, a plurality of vertically extending spikes arranged inside the sole arrangement such that the spikes are moveable relative to the lower sole member, said lower sole member having a plurality of holes adapted to receive the spikes as to allow the spikes to protrude from the lower sole member in a downward direction, a locking sole member located between the upper and lower sole members, a spacer extending vertically from one of said sole members, and an opening arranged on one of the other of said sole members, said opening being adapted to receive the spacer, said spacer and spacer-receiving opening being arranged to face each other as to allow interaction between the two sole members equipped with the spacer and the spacer-receiving opening, respectively, said locking sole member being movably arranged as to allow a relative movement between the spacer and the spacer-receiving opening in a substantially horizontal direction, said locking sole member being adapted to be moved between: a first position wherein the spacer and the spacer-receiving opening are at least partly displaced such that the spacer defines a minimum distance between the two interacting sole members, and a second position wherein the spacer and the spacer-receiving opening are aligned in such a way that the spacer-receiving opening is capable of receiving the spacer allowing the two interacting sole members to come closer to each other than the minimum distance.
