Abstract
The shoe includes a shoe upper and a sole connected to the shoe upper. The sole includes an upper sole element, and a lower sole element. The shoe also includes an elongated spring element attached at both ends to the shoe upper, or attached at one to the shoe upper and the other end to the upper side element. The elongated spring element exerts a force on the upper sole element to pull the upper sole element away from the lower sole element. The upper sole element has a surface on which the sole of a foot of a wearer of the shoe rests during use of the shoe. The upper sole element rests on the lower sole element during use of the shoe due to the weight of the wearer of the shoe. The elongated spring element pulls at least a part of the upper sole element away from the lower sole element to separate the part of the upper sole element from the lower sole element, during non-use of the shoe. The elongated spring element can be a rubber band.
